GPIO3

Control

GP3_DIR

GPIO3 Pin Direction

0 = Output

1 = Input

14:13

GP3_PULL[1:0]

GPIO3 pull-up / pull-down Enable

00 = no pull-up or pull-down

01 = pull-down

10 = pull-up

11 = reserved

GP3_INT_MOD

GPIO3 Interrupt Mode

0 = GPIO interrupt is rising edge triggered (if

GP3_POL=0) or falling edge triggered (if GP3_POL =1)

1 = GPIO interrupt is triggered on rising and falling

edges

GP3_POL

GPIO3 Polarity Select

0 = Non-inverted

1 = Inverted

GP3_LVL

GPIO3 level. Write to this bit to set a GPIO output.

Read from this bit to read GPIO input level.

When GP3_POL is set, the register contains the

opposite logic level to the external pin.
