I/O
I/O pins for the main clock generation circuit. Connect a ceramic resonator or
crystal oscillator between XIN and XOUT
(3)
. To use 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
(3)
. 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.)

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