EMC1=DONOTHING, EMC0=DONOTHING, EMC2=DONOTHING, EMC3=DONOTHING
External Match Register (EMR). The EMR controls the match function and the external match pins CT16B0_MAT[2:0].
| EM0 | External Match 0. This bit reflects the state of output CT16B0_MAT0/CT16B1_MAT0, whether or not this output is connected to its pin. When a match occurs between the TC and MR0, this bit can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[5:4] control the functionality of this output. This bit is driven to the CT16B0_MAT0/CT16B1_MAT0 pins if the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH). |
| EM1 | External Match 1. This bit reflects the state of output CT16B0_MAT1/CT16B1_MAT1, whether or not this output is connected to its pin. When a match occurs between the TC and MR1, this bit can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[7:6] control the functionality of this output. This bit is driven to the CT16B0_MAT1/CT16B1_MAT1 pins if the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH). |
| EM2 | External Match 2. This bit reflects the state of output match channel 2, whether or not this output is connected to its pin. When a match occurs between the TC and MR2, this bit can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[9:8] control the functionality of this output. Note that on counter/timer 0 this match channel is not pinned out. This bit is driven to the CT16B1_MAT2 pin if the match function is selected in the IOCON registers (0 = LOW, 1 = HIGH). |
| EM3 | External Match 3. This bit reflects the state of output of match channel 3. When a match occurs between the TC and MR3, this bit can either toggle, go LOW, go HIGH, or do nothing. Bits EMR[11:10] control the functionality of this output. There is no output pin available for this channel on either of the 16-bit timers. |
| EMC0 | External Match Control 0. Determines the functionality of External Match 0. 0 (DONOTHING): Do Nothing. 1 (CLEAR): Clear the corresponding External Match bit/output to 0 (CT16Bn_MATm pin is LOW if pinned out). 2 (SET): Set the corresponding External Match bit/output to 1 (CT16Bn_MATm pin is HIGH if pinned out). 3 (TOGGLE): Toggle the corresponding External Match bit/output. |
| EMC1 | External Match Control 1. Determines the functionality of External Match 1. 0 (DONOTHING): Do Nothing. 1 (CLEAR): Clear the corresponding External Match bit/output to 0 (CT16Bn_MATm pin is LOW if pinned out). 2 (SET): Set the corresponding External Match bit/output to 1 (CT16Bn_MATm pin is HIGH if pinned out). 3 (TOGGLE.): Toggle the corresponding External Match bit/output. |
| EMC2 | External Match Control 2. Determines the functionality of External Match 2. 0 (DONOTHING): Do Nothing. 1 (CLEAR): Clear the corresponding External Match bit/output to 0 (CT16Bn_MATm pin is LOW if pinned out). 2 (SET): Set the corresponding External Match bit/output to 1 (CT16Bn_MATm pin is HIGH if pinned out). 3 (TOGGLE): Toggle the corresponding External Match bit/output. |
| EMC3 | External Match Control 3. Determines the functionality of External Match 3. 0 (DONOTHING): Do Nothing. 1 (CLEAR): Clear the corresponding External Match bit/output to 0 (CT16Bn_MATm pin is LOW if pinned out). 2 (SET): Set the corresponding External Match bit/output to 1 (CT16Bn_MATm pin is HIGH if pinned out). 3 (TOGGLE): Toggle the corresponding External Match bit/output. |
| RESERVED | Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined. |
