GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 Direction
These bits permit the user to define the General Purpose I/O Pins,
GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 as either Input pins or Output
pins, as described below.
0 – Configures GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 to function as
input pins.
1 – Configures GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 to function as
output pins.
1. If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to
function as input pins, then the user can monitor the state of
these input pins by reading out the state of Bit 3-0 (GPIO0_3/
GPIO0_2/GPIO0_1/GPIO0_0) within this register.
2. If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to
function as output pins, then the user can control the state of
these output pins by writing the appropriate value into Bit 3-0
(GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0) within this register.

GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 Control
The exact function of this bit depends upon whether General Purpose I/
O Pins, GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 have been configured
to function as input or output pins, as described below.
If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to function
as input pins:
If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to function as
input pins, then the user can monitor the state of the corresponding
input pin by reading out the state of these bits.
NOTE:
If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to
function as input pins, then writing to this particular register will
have no effect on the state of this pin.
If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to function
as output pins:
If GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 are configured to function as
output pins, then the user can control the state of the corresponding
output pin by writing the appropriate value to these bits.
NOTE:
GPIO0_3/GPIO0_2/GPIO0_1/GPIO0_0 can be configured to
function as input or output pins, by writing the appropriate
value to Bit 7-4 (GPIO0_3DIR/GPIO0_2DIR/GPIO0_1DIR/
GPIO0_0DIR) within this register.
