Description
Writes to this register provide data to the output buffer enables. A
value of 1 enables the driver.
Description
Writes to this register provide data to the mux selects on the input
buffers. A value of 0 selects the direct input data to be read for
GPDATA. A value of 1 selects the registered input for GPDATA. Data
on the GPIO pins is registered upon the programmable edge of
GPWE.
Description
Writes to this register provide data to the output buffers. Read data is
from the input buffer. Data from this register can only be read if output
enables are set and GPIOMODE is set to normal.
