45.3.2 RGPIO Data Direction Register (RGPIO_DIR)
Reading this read-only register returns the value of the RGPIO_DIR register at offset 0h.
Address: RGPIO_DIR is C00000h base + 8h offset = 00C0_0008h
45.3.6 RGPIO Set Data Register (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.
Address: RGPIO_SET is C00000h base + Ah offset = 00C0_000Ah
