Description

Pin configuration register for pins P9

Fields

MODE

Select pin function

0 (FUNCTION_0_DEFAULT): Function 0 (default)

1 (FUNCTION_1): Function 1

2 (FUNCTION_2): Function 2

3 (FUNCTION_3): Function 3

4 (FUNCTION_4): Function 4

5 (FUNCTION_5): Function 5

6 (FUNCTION_6): Function 6

7 (FUNCTION_7): Function 7

EPD

Enable pull-down resistor at pad

0 (DISABLE_PULL_DOWN_): Disable pull-down.

1 (ENABLE_PULL_DOWN_): Enable pull-down.

EPUN

Disable pull-up resistor at pad. By default, the pull-up resistor is enabled at reset.

0 (ENABLE_PULL_UP): Enable pull-up

1 (DISABLE_PULL_UP): Disable pull-up

EHS

Slew rate

0 (SLOW): Slow

1 (FAST): Fast

EZI

Input buffer enable. The input buffer is disabled by default at reset but must be enabled to transfer data from the I/O buffer to the pad.

0 (DISABLE_INPUT_BUFFER): Disable input buffer

1 (ENABLE_INPUT_BUFFER): Enable input buffer

RESERVED

Reserved

EHD

Select drive strength

0 (STANDARD_DRIVE_4_MA): Standard drive: 4 mA drive strength

1 (MEDIUM_DRIVE_8_MA_D): Medium drive: 8 mA drive strength

2 (HIGH_DRIVE_14_MA_DR): High drive: 14 mA drive strength

3 (ULTRA_HIGH_DRIVE_20): Ultra-high drive: 20 mA drive strength
