Memory Map and Registers
At reset, all bits in the RGPIO_ENB register are cleared, disabling the RGPIO
functionality.
Address: RGPIO_ENB is C00000h base + 4h offset = 00C0_0004h
45.3.5 RGPIO Clear Data Register (RGPIO_CLR)
The RGPIO_CLR register provides a mechanism to clear specific bits in the
RGPIO_DATA by performing a simple write. Clearing a bit in RGPIO_CLR clears the
corresponding bit in the RGPIO_DATA register. Setting it has no effect. The
RGPIO_CLR register is write-only; reads of this address return the RGPIO_DATA
register.
Address: RGPIO_CLR is C00000h base + 6h offset = 00C0_0006h
