Description

Digital I/O control for port 2 pins PIO2_0 to PIO2_13. Without glitch filter.

Fields

RESERVED

Reserved. Only write 0 to these bits.

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.

OD

Open-drain mode.

0 (DISABLE): Disable.

1 (OPEN_DRAIN_MODE_ENAB): Open-drain mode enabled. This is not a true open-drain mode.

S_MODE

Digital filter sample mode.

0 (BYPASS_INPUT_FILTER): Bypass input filter.

1 (1_CLOCK_CYCLE): 1 clock cycle. Input pulses shorter than one filter clock are rejected.

2 (2_CLOCK_CYCLES): 2 clock cycles. Input pulses shorter than two filter clocks are rejected.

3 (3_CLOCK_CYCLES): 3 clock cycles. Input pulses shorter than three filter clocks are rejected.

CLKDIV

Select peripheral clock divider for input filter sampling clock IOCONCLKDIV. Value 0x7 is reserved.

0 (CMP_PCLK): CMP_PCLK.

1 (CMP_PCLKDIV2): CMP_PCLK/2.

2 (CMP_PCLKDIV4): CMP_PCLK/4.

3 (CMP_PCLKDIV8): CMP_PCLK/8.

4 (CMP_PCLKDIV16): CMP_PCLK/16.

5 (CMP_PCLKDIV32): CMP_PCLK/32.

6 (CMP_PCLKDIV64): CMP_PCLK/64.

RESERVED

Reserved.
