XR21V1414
4-CH FULL-SPEED USB UART
Writing a ’1’ in this register drives the GPIO output high. Writing a ’0’ to a bit has no effect. Bits 7-6 are unused
and should be ’0’.
Writing a ’1’ in this register drives the GPIO output low. Writing a ’0’ to a bit has no effect. Bits 7-6 are unused
and should be ’0’.
This register reports the current state of the GPIO pin.
