25.4.1.18 GPIO_DATAOUT Register (offset = 13Ch) [reset = 0h]
GPIO_DATAOUT is shown in Figure 25-24 and described in Table 25-23.
The GPIO_DATAOUT register is used for setting the value of the GPIO output pins. Data is written to the
GPIO_DATAOUT register synchronously with the interface clock. This register can be accessed with
direct read/write operations or using the alternate Set/Clear feature. This feature enables to set or clear
specific bits of this register with a single write access to the set data output register
(GPIO_SETDATAOUT) or to the clear data output register (GPIO_CLEARDATAOUT) address.
