GPIO Output Enable Register

This register is used to enable or disable output function of GPIO. These registers are no use for those pins which are

GPI only. Also if alternative output selected, this register is no effect on corresponding GPIO pin. For those

GPXA00~GPAX18 can be utilized as GPO function.

(0:Disable Output 1:Enable Output)

In bitmap, where I for GPI only, O for GPO only, and I/O for GPIO.
