Memory Map and Registers
45.3.8 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 + Ch offset = 00C0_000Ch
45.3.7 RGPIO Toggle Data Register (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.
Address: RGPIO_TOG is C00000h base + Eh offset = 00C0_000Eh
