GPIO2

Control

GP2_DIR

GPIO2 Pin Direction

0 = Output

1 = Input

14:13

GP2_PULL [1:0]

GPIO2 pull-up / pull-down Enable

00 = no pull-up or pull-down

01 = pull-down

10 = pull-up

11 = reserved

GP2_INT_

MODE

GPIO2 Interrupt Mode

0 = GPIO interrupt is rising edge triggered (if GP2_POL=0)

or falling edge triggered (if GP2_POL =1)

1 = GPIO interrupt is triggered on rising and falling edges

GP2_POL

GPIO2 Polarity Select

0 = Non-inverted

1 = Inverted

GP2_LVL

GPIO2 level. Write to this bit to set a GPIO output. Read

from this bit to read GPIO input level.

When GP2_POL is set, the register contains the opposite

logic level to the external pin.

GP2_FN [3:0]

0000

GPIO2 Pin Function

0000 = Logic Level Input

0001 = Edge Detection Input

0010 = CLKOUT output

0011 = Interupt (IRQ) output

0100 = Reserved

0101 = Reserved

0110 = Reserved

0111 = Temperature flag output

1000 = Reserved

1001 = DMICCLK output

1010 = Logic Level output

1011 = LDO_UV output

Interrupts

(Read only)

TEMP_INT

Thermal Interrupt status (Read only)

0 = Thermal interrupt not set

1 = Thermal interrupt set

This bit is latched when set; it is cleared when the register

is Read.

GP2_INT

GPIO2 Interrupt status (Read only)

0 = GPIO2 interrupt not set

1 = GPIO2 interrupt set

This bit is latched when set; it is cleared when the register
