Address & Name
GPIO Port Pin value register. The current state of the port
0xE0028010
pins can always be read from this register, regardless of
IO1PIN
pin direction and mode.
GPIO Port Output set register. This register controls the
0xE0028014 state of output pins in conjunction with the IOCLR
IO1SET register. Writing ones produces highs at the
corresponding port pins. Writing zeroes has no effect.
0xE0028018 GPIO Port Direction control register. This register
IO1DIR individually controls the direction of each port pin.
GPIO Port Output clear register. This register controls
0xE002801C the state of output pins. Writing ones produces lows at
IO1CLR the corresponding port pins and clears the corresponding
bits in the IOSET register. Writing zeroes has no effect.
