I/O configuration register for pin PIO0_23/RTS/ ACMP_O/ CT32B0_CAP0/SCLK
| FUNC | Selects pin function for pin PIO0_23/RTS/ ACMP_O/ CT32B0_CAP0/SCLK 0 (PIO0_23): General purpose digital input/output pin. 1 (RTS): Request To Send output for USART. 2 (ACMP_O): Analog comparator output. 3 (CT32B0_CAP0): Capture input 0 for 32-bit timer 0. 4 (SCLK): Serial clock for USART. |
| MODE | Selects function mode (on-chip pull-up/pull-down resistor control). 0 (INACTIVE_NO_PULL_DO): Inactive (no pull-down/pull-up resistor enabled). 1 (PULL_DOWN_RESISTOR_E): Pull-down resistor enabled. 2 (PULL_UP_RESISTOR_ENA): Pull-up resistor enabled. 3 (REPEATER_MODE_): Repeater mode. |
| HYS | Hysteresis. 0 (DISABLE_): Disable. 1 (ENABLE_): Enable. |
| INV | Invert input 0 (INPUT_NOT_INVERTED_): Input not inverted (HIGH on pin reads as 1, LOW on pin reads as 0). 1 (INPUT_INVERTED_HIGH): Input inverted (HIGH on pin reads as 0, LOW on pin reads as 1). |
| ADMODE | Selects Analog/Digital mode. 0 (ANALOG_INPUT_MODE_): Analog input mode. 1 (DIGITAL_FUNCTIONAL_M): Digital functional mode. |
| FILTR | Selects 10 ns input glitch filter. 0 (FILTER_DISABLED_): Filter disabled. 1 (FILTER_ENABLED_): Filter enabled. |
| RESERVED | Reserved. |
| OD | Open-drain mode. 0 (DISABLE_): Disable. 1 (OPEN_DRAIN_MODE_ENAB): Open-drain mode enabled. This is not a true open-drain mode. |
