Read and write
This register controls the P0.0, P0.1, P0.2, and
P0.3 functionality of the multifunction GPIO
pins.
0xFFFF0468
Reserved.
General I/O port pin functionality lock
registers.
GPL[7:0] = 1, for each GPIO pin, if this bit is
set, writing to the corresponding bit in
GPxCON or GPxDAT register bit has no
effect.

configurable.
Pull-Up Disable Port x[7:0].
Description
GPL[7:0] = 0, normal operation.
GPDS[x] = 0, maximum source current is 2 mA.
GPDS[x] = 1, maximum source current is 4 mA.
GPPD[x] = 0, pull-up resistor is active.
GPPD[x] = 1, pull-up resistor is disabled.

Write only
When writing to GP0CON1, the value of 0x07
must be written to this register in the
instruction immediately before writing to
GP0CON1.
GP0KEY2
0xFFFF046C
0xXXXX
Write only
When writing to GP0CON1, the value of 0x13
must be written to this register in the instruction
immediately after writing to GP0CON1.

To select the P0.0, P0.1, P0.2, and P0.3
functions in SPI mode, clear this bit to 0.
To select the P0.0, P0.1, P0.2, and P0.3
functions in I
This bit configures the P0.0 to P0.3 functions
as GPIO pins or as ADC input pins.
To enable P0.0, P0.1, P0.2 and P0.3 functions
as ADC inputs, set this bit to 1.
To enable P0.0, P0.1, P0.2, and P0.3 functions
as digital I/O, clear this bit to 0.
Description
These bits must always be set to 0.
