NOTES:
1. When use VCC1 > VCC2, contacts due to some points or restrictions to be checked.
2. This pin function in M16C/62PT cannot be used.
3. Ask the oscillator maker the oscillation characteristic.

I/O pins for the main clock generation circuit. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT
the external clock, input the clock from XIN and leave XOUT open.
I/O pins for a sub clock oscillation circuit. Connect a crystal
oscillator between XCIN and XCOUT
input the clock from XCIN and leave XCOUT open.
Outputs the BCLK signal.
The clock of the same cycle as fC, f8, or f32 is outputted.
Input pins for the INT interrupt.
Input pin for the NMI interrupt. Pin states can be read by the P8_5
bit in the P8 register.
Input pins for the key input interrupt.
These are timer A0 to timer A4 I/O pins. (however, output of
TA0OUT for the N-channel open drain output.)
These are timer A0 to timer A4 input pins.
Input pin for the Z-phase.
These are timer B0 to timer B5 input pins.
These are Three-phase motor control output pins.
These are send control input pins.
These are receive control output pins.
These are transfer clock I/O pins.
These are serial data input pins.
These are serial data input pins.
These are serial data output pins. (however, output of TXD2 for the
N-channel open drain output.)
These are serial data output pins.
This is output pin for transfer clock output from multiple pins
function.
These are serial data I/O pins. (however, output of SDA2 for the N-
channel open drain output.)
These are transfer clock I/O pins. (however, output of SCL2 for the
N-channel open drain output.)
