Slew Rate Enable
Description
Slew Rate configuration is valid in all digital pin muxing modes.
0 Fast slew rate is configured on the corresponding pin, if pin is configured as a digital output.
1 Slow slew rate is configured on the corresponding pin, if pin is configured as a digital output.

Pull Enable
PE
Pull configuration is valid in all digital pin muxing modes.
0 Internal pull-up or pull-down resistor is not enabled on the corresponding pin.
1 Internal pull-up or pull-down resistor is enabled on the corresponding pin, provided pin is configured
as a digital input.
0
Pull Select
PS
Pull configuration is valid in all digital pin muxing modes.
0 Internal pull-down resistor is enabled on the corresponding pin, if the corresponding Port Pull Enable
Register bit is set.
1 Internal pull-up resistor is enabled on the corresponding pin, if the corresponding Port Pull Enable
Register bit is set.

Global Pin Write Enable
Description
When set, causes bits [15:0] of the corresponding Pin Control Register (15 through 0) to update with the
value in the Global Pin Write Data field.
Global Pin Write Data
Value to be written to bits [15:0] of all Pin Control Registers that are enabled by the Global Pin Write
Enable field, provided the corresponding register has not been locked.
