Description
(1)
Main clock
input
XIN
I
VCC1 I/O pins for the main clock generation circuit. Connect a ceramic
(3)
resonator or crystal oscillator between XIN and XOUT . To use
the external clock, input the clock from XIN and leave XOUT open.
Main clock
output
XOUT
O
VCC1
Sub clock input XCIN
I
VCC1 I/O pins for a sub clock oscillation circuit. Connect a crystal
(3)
oscillator between XCIN and XCOUT . To use the external clock,
input the clock from XCIN and leave XCOUT open.
Sub clock
output
XCOUT
O
VCC1
(2)
BCLK output

I
NMI interrupt
input
VCC1 Input pin for the NMI interrupt. Pin states can be read by the P8_5
bit in the P8 register.
Key input
interrupt input
I
I/O
I
VCC1 Input pins for the key input interrupt.

VCC1 These are transfer clock I/O pins. (however, output of SCL2 for the
N-channel open drain output.)
I : Input O : Output I/O : Input and output
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.
