Pin Control Register n
| PS | Pull Select 0 (0): Internal pulldown resistor is enabled on the corresponding pin, if the corresponding Port Pull Enable Register field is set. 1 (1): Internal pullup resistor is enabled on the corresponding pin, if the corresponding Port Pull Enable Register field is set. |
| PE | Pull Enable 0 (0): Internal pullup or pulldown resistor is not enabled on the corresponding pin. 1 (1): Internal pullup or pulldown resistor is enabled on the corresponding pin, if the pin is configured as a digital input. |
| SRE | Slew Rate Enable 0 (0): Fast slew rate is configured on the corresponding pin, if the pin is configured as a digital output. 1 (1): Slow slew rate is configured on the corresponding pin, if the pin is configured as a digital output. |
| PFE | Passive Filter Enable 0 (0): Passive input filter is disabled on the corresponding pin. 1 (1): Passive input filter is enabled on the corresponding pin, if the pin is configured as a digital input. A low pass filter (10 MHz to 30 MHz bandwidth) is enabled on the digital input path. Disable the passive input filter when supporting high speed interfaces (> 2 MHz) on the pin. |
| ODE | Open Drain Enable 0 (0): Open drain output is disabled on the corresponding pin. 1 (1): Open drain output is enabled on the corresponding pin, if the pin is configured as a digital output. |
| DSE | Drive Strength Enable 0 (0): Low drive strength is configured on the corresponding pin, if pin is configured as a digital output. 1 (1): High drive strength is configured on the corresponding pin, if pin is configured as a digital output. |
| MUX | Pin Mux Control 0 (000): Pin disabled (analog). 1 (001): Alternative 1 (GPIO). 2 (010): Alternative 2 (chip-specific). 3 (011): Alternative 3 (chip-specific). 4 (100): Alternative 4 (chip-specific). 5 (101): Alternative 5 (chip-specific). 6 (110): Alternative 6 (chip-specific). 7 (111): Alternative 7 (chip-specific/JTAG/NMI). |
| LK | Lock Register 0 (0): Pin Control Register fields [15:0] are not locked. 1 (1): Pin Control Register fields [15:0] are locked and cannot be updated until the next system reset. |
| IRQC | Interrupt Configuration 0 (0000): Interrupt/DMA request disabled. 1 (0001): DMA request on rising edge. 2 (0010): DMA request on falling edge. 3 (0011): DMA request on either edge. 8 (1000): Interrupt when logic zero. 9 (1001): Interrupt on rising edge. 10 (1010): Interrupt on falling edge. 11 (1011): Interrupt on either edge. 12 (1100): Interrupt when logic one. |
| ISF | Interrupt Status Flag 0 (0): Configured interrupt has not been detected. 1 (1): Configured interrupt has been detected. If the pin is configured to generate a DMA request, then the corresponding flag will be cleared automatically at the completion of the requested DMA transfer. Otherwise, the flag remains set until a logic one is written to the flag. If the pin is configured for a level sensitive interrupt that remains asserted, then the flag will set again immediately. |
