GPWE
Global Pin Write Enable
Selects which Pin Control Registers (15 through 0) bits [15:0] update with the value in GPWD. If a
selected Pin Control Register is locked then the write to that register is ignored.
0 Corresponding Pin Control Register is not updated with the value in GPWD.
1 Corresponding Pin Control Register is updated with the value in GPWD.
GPWD Global Pin Write Data
Write value that is written to all Pin Control Registers bits [15:0] that are selected by GPWE.
