INV=INPUT_NOT_INVERTED_, OD=DISABLE_, MODE=INACTIVE_NO_PULL_DO, SLEW=SLOW, HYS=DISABLE_, FUNC=PIO1_9
I/O configuration register for pin PIO1_9/DCD/R/ CT32B1_MAT2 / CT16B1_MAT2
| FUNC | Selects pin function for pin PIO1_9/DCD/R/ CT32B1_MAT2 / CT16B1_MAT2 0 (PIO1_9): General purpose digital input/output pin. 1 (DCD): Data Carrier Detect input for USART. 2 ®: Reserved. 3 (CT32B1_MAT2): Match output 2 for 32-bit timer 1. 4 (CT16B1_MAT2): Match output 2 for 16-bit timer 1. |
| 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). |
| RESERVED | Reserved. |
| SLEW | Driver slew rate 0 (SLOW): Slow. More outputs can be switched simultaneously. 1 (FAST): Fast. |
| OD | Open-drain mode. 0 (DISABLE_): Disable. 1 (OPEN_DRAIN_MODE_ENAB): Open-drain mode enabled. This is not a true open-drain mode. Input cannot be pulled up above VDD. |
