Access Mode.......Read/Write

Width ...................16 bits

DebugCtrl selects the functions of the GPIO pins. DebugCtrl is cleared by reset.

BIT BIT NAME BIT DESCRIPTION

0 GPIO0Ctrl This bit controls the GPIO0 pin. When cleared, GPIO0 pin is an input.

When set, GPIO0 pin is an output. This bit is cleared on reset.

1 GPIO1Ctrl This bit controls the GPIO1 pins. When cleared, GPIO1 pin is an input.

When set, GPIO1 pin is an output. This bit is cleared on reset.

2 GPIO0 When read, this bit shows the status values of the GPIO0 pin. When

written into, this bit will drive the GPIO0 pin if GPIO0Ctrl is set, and

GPIO0 pin functions as an output.

3 GPIO1 When read, this bit shows the status values of the GPIO1 pin. When

written into, this bit will drive the GPIO1 pin if GPIO1Ctrl is set, and

GPIO1 pin functions as an output.
