VCC,
Power source
Apply voltage of 5 V
± 10 % to (typical) VCC, and 0 V to VSS.
VSS.
CNVSS
This is connected to VSS.
______
RESET
Reset input
Input
To enter the reset state, the reset input pin must be kept at a “L” for 2
s or more (under
normal VCC conditions).
If more time is needed for the quartz-crystal oscillator to stabilize, this “L” condition should
be maintained for the required time.
XIN
Clock input
Input
This chip has an internal clock generating circuit. To control generating frequency, an
external ceramic resonator or a quartz-crystal oscillator is connected between pins XIN and
XOUT
Clock output
Output
XOUT. If an external clock is used, the clock source should be connected to the XIN pin and
the XOUT pin should be left open.
P00/PWM4– I/O port P0
I/O
Port P0 is an 8-bit I/O port with direction register allowing each I/O bit to be individually
