17.2.9 PORTXT data input register (PXTDI)
PXTDI is a special function register (SFR) used for reading the level of XT0/XT1 pin.
The level of XT0/PI00 and XT1/PI01 is readable in the input mode.
Set PXT0IE bit and PXT1IE bit of PXTMOD01 register for switching the port to the input mode.
The port is unavailable to use when connecting the crystal resonator.

PXT1DI
This bit is used for reading the level of XT1/PI01.
0: The input level of XT1/PI01 pin is “L”
1: The input level of XT1/PI01 pin is “H”
0
PXT0DI
This bit is used for reading the level of XT0/PI00.
0: The input level of XT0/PI00 pin is
“
L”
1: The input level of XT0/PI00 pin is “H”
[Note]
Ÿ
PI00 and PI01 are unavailable to use as input ports when using the crystal resonator for the oscillation
clock.
Also, PI01 is unavailable to use as an input port when using the PI01 for the external clock input.
See Chapter 6 “Clock Generation Circuit” for more details on how to use the crystal oscillation or
external clock input.
