Value
Each GPIO port A pin (GPIO0-GPIO31) corresponds to one bit in this register.
0 Writes of 0 are ignored. This register always reads back a 0.
1 Writing a 1 forces the respective output data latch to high. If the pin is configured as a GPIO
output then it will be driven high. If the pin is not configured as a GPIO output then the latch is set
high but the pin is not driven.
Value
Each GPIO port A pin (GPIO0-GPIO31) corresponds to one bit in this register.
0 Writes of 0 are ignored. This register always reads back a 0.
1 Writing a 1 forces the respective output data latch to low. If the pin is configured as a GPIO output
then it will be driven low. If the pin is not configured as a GPIO output then the latch is cleared but
the pin is not driven.
Value
Each GPIO port A pin (GPIO0-GPIO31) corresponds to one bit in this register.
0 Writes of 0 are ignored. This register always reads back a 0.
1 Writing a 1 forces the respective output data latch to toggle from its current state. If the pin is
configured as a GPIO output then it will be driven in the opposite direction of its current state. If the
pin is not configured as a GPIO output then the latch is toggled but the pin is not driven.
