GPIO Registers
25.4.1.16 GPIO_OE Register (offset = 134h) [reset = FFFFFFFFh]
GPIO_OE is shown in
and described in
The GPIO_OE register is used to enable the pins output capabilities. At reset, all the GPIO related pins
are configured as input and output capabilities are disabled. This register is not used within the module, its
only function is to carry the pads configuration. When the application is using a pin as an output and does
not want interrupt generation from this pin, the application can/has to properly configure the Interrupt
Enable registers.
