GPIO Data Out Register (GPDO)
GPIO Data In Register (GPDI)
Data Out. Bits 7-0 correspond to pins 7-0 respectively. The value of each bit determines the value driven on the
corresponding GPIO pin when its output buffer is enabled. Writing to the bit latches the written data unless the
bit is locked by the GPCFG register Lock bit. Reading the bit returns its value, regardless of the pin value and
configuration.
0: Corresponding pin driven to low when output enabled
1: Corresponding pin driven or released to high (according to buffer type and static pull-up selection) when
Data In. Bits 7-0 correspond to pins 7-0 respectively. Reading each bit returns the value of the corresponding
GPIO pin, regardless of the pin configuration and the GPDO register value. Write is ignored.
0: Corresponding pin level low
1: Corresponding pin level high
