17.3.5
The RGPIO_SET register provides a mechanism to set specific bits in the RGPIO_DATA register by
performing a simple write. Setting a bit in RGPIO_SET asserts the corresponding bit in the RGPIO_DATA
register. Clearing it has no effect. The RGPIO_SET register is write-only; reads of this address return the
RGPIO_DATA register.
17.3.6
The RGPIO_TOG register provides a mechanism to invert (toggle) specific bits in the RGPIO_DATA
register by performing a simple write. Setting a bit in RGPIO_TOG inverts the corresponding bit in the
RGPIO_DATA register. Clearing it has no effect. The RGPIO_TOG register is write-only; reads of this
address return the RGPIO_DATA register.
