Chapter 9 Rapid GPIO (RGPIO)
Figure 9-7. RGPIO Clear Data Register (RGPIO_CLR)
9.3.2.5 RGPIO Set Data (RGPIO_SET)
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.

9.3.2.6 RGPIO Toggle Data (RGPIO_TOG)
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.
