Module Control
| BUSYF | Start and Busy Flag. 0 (IDLE): Read: A capacitive sensing conversion is complete or a conversion is not currently in progress. Write: No effect. 1 (BUSY): Read: A capacitive sensing conversion is in progress. Write: Initiate a capacitive sensing conversion if BUSYF is selected as the start of conversion source. |
| CSEN | Module Enable. 0 (DISABLED): Disable the capacitive sensing module. 1 (ENABLED): Enable the capacitive sensing module. |
| BIASEN | Bias Enable. 0 (DISABLED): Disable the bias. 1 (ENABLED): Enable the bias. |
| CMPPOL | Digital Comparator Polarity Select. 0 (GT): The digital comparator generates an interrupt if the conversion is greater than the CSTH threshold. 1 (LTE): The digital comparator generates an interrupt if the conversion is less than or equal to the CSTH threshold. |
| CMD | Conversion Mode Select. 0 (SINGLE): Single Conversion Mode: One conversion occurs on a single channel. 1 (SCAN): Single Scan Mode: One conversion on each channel selected by SCANEN occurs. An end-of-scan interrupt indicates all channels have been measured. 2 (CONT_SINGLE): Continuous Single Conversion Mode: Continuously converts on a single channel. This operation ends only if the module is disabled (CSEN = 0) or if a compare threshold event occurs (CMPI = 1). 3 (CONT_SCAN): Continuous Scan Mode: Continuously loops through and converts on all the channels selected by SCANEN. This operation ends only if the module is disabled (CSEN = 0) or if a compare threshold event occurs (CMPI = 1). |
| CNVR | Conversion Rate. 0 (12BIT): Conversions last 12 internal CAPSENSE clocks and results are 12 bits in length. 1 (13BIT): Conversions last 13 internal CAPSENSE clocks and results are 13 bits in length. 2 (14BIT): Conversions last 14 internal CAPSENSE clocks and results are 14 bits in length. 3 (16BIT): Conversions last 16 internal CAPSENSE clocks and results are 16 bits in length. |
| ACCMD | Accumulator Mode Select. 0 (ACC_1): Accumulate 1 sample. 1 (ACC_4): Accumulate 4 samples. 2 (ACC_8): Accumulate 8 samples. 3 (ACC_16): Accumulate 16 samples. 4 (ACC_32): Accumulate 32 samples. 5 (ACC_64): Accumulate 64 samples. |
| MCEN | Multiple Channel Enable. 0 (DISABLED): Disable the multiple channel measurement feature. 1 (ENABLED): Enable the multiple channel measurement feature. |
| CSCM | Start of Conversion Mode Select. 0 (CSNT0): The CSnT0 (“On Demand” by writing 1 to CSBUSY) trigger source starts conversions. 1 (CSNT1): The CSnT1 (Timer 0 Low Overflow) trigger source starts conversions. 2 (CSNT2): The CSnT2 (Timer 0 High Overflow) trigger source starts conversions. 3 (CSNT3): The CSnT3 (Timer 1 Low Overflow) trigger source starts conversions. 4 (CSNT4): The CSnT4 (Timer 1 High Overflow) trigger source starts conversions. 5 (CSNT5): The CSnT5 (I2C0 Timer Byte 1 Overflow) trigger source starts conversions. 6 (CSNT6): The CSnT6 (I2C0 Timer Byte 3 Overflow) trigger source starts conversions. 7 (CSNT7): The CSnT7 (I2C1 Timer Byte 1 Overflow) trigger source starts conversions. 8 (CSNT8): The CSnT8 (I2C1 Timer Byte 3 Overflow) trigger source starts conversions. 9 (CSNT9): The CSnT9 (RESERVED) trigger source starts conversions. 10 (CSNT10): The CSnT10 (RESERVED) trigger source starts conversions. 11 (CSNT11): The CSnT11 (RESERVED) trigger source starts conversions. 12 (CSNT12): The CSnT12 (RESERVED) trigger source starts conversions. 13 (CSNT13): The CSnT13 (RESERVED) trigger source starts conversions. 14 (CSNT14): The CSnT14 (RESERVED) trigger source starts conversions. 15 (CSNT15): The CSnT15 (RESERVED) trigger source starts conversions. |
| PMMD | Pin Monitor Mode. 0 (ALWAYS_RETRY): Always retry on a pin state change. 1 (RETRY_TWICE): Retry up to twice on consecutive bit cycles. 2 (RETRY_FOUR_TIMES): Retry up to four times on consecutive bit cycles. 3 (DO_NOT_RETRY): Ignore monitored signal state change. |
| PMEF | Pin Monitor Event Flag. 0 (NOT_SET): A retry did not occur due to a pin monitor event during the last conversion. 1 (SET): A retry occurred due to a pin monitor event during the last conversion. |
| CMPEN | Threshold Comparator Enable. 0 (DISABLED): Disable the threshold comparator. 1 (ENABLED): Enable the threshold comparator. |
| CDIEN | Conversion Done Interrupt Enable. 0 (DISABLED): Disable the single conversion done interrupt. 1 (ENABLED): Enable the single conversion done interrupt. |
| EOSIEN | End-of-Scan Interrupt Enable. 0 (DISABLED): Disable the single scan end-of-scan interrupt. 1 (ENABLED): Enable the single scan end-of-scan interrupt. |
| CMPI | Threshold Comparator Interrupt Flag. 0 (NOT_SET): The capacitive sensing result did not cause a compare threshold interrupt. 1 (SET): The capacitive sensing result caused a compare threshold interrupt. |
| CDI | Conversion Done Interrupt Flag. 0 (NOT_SET): Read: The CAPSENSEn module has not completed a data conversion since the last time CDI was cleared. Write: Clear the interrupt. 1 (SET): Read: The CAPSENSEn module completed a data conversion. Write: Force a conversion complete interrupt. |
| EOSI | End-of-Scan Interrupt Flag. 0 (NOT_SET): The CAPSENSEn module has not completed a scan since the last time EOSI was cleared. 1 (SET): The CAPSENSEn module completed a scan. |
