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
clock from XIN and leave XOUT open.
I/O pins for a sub clock oscillation circuit. Connect a crystal oscillator between

XCIN and XCOUT
. To use the external clock, 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. (except the output of TAOUT 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. (except 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. (except SDA2 for the N-channel open drain
output.)
These are transfer clock I/O pins. (except SCL2 for the N-channel open drain
output.)
