Output
Apply voltage of 5 V ± 10 % (typical) to V
This is connected to V
Input To enter the reset state, the reset input pin must be kept at a "L" for
2 µ s or more (under normal V
If more time is needed for the quartz-crystal oscillator to stabilize, this
"L" condition should be maintained for the required time.
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 X
Output
the clock source should be connected to the X

I/O
Port P0 is an 8-bit I/O port with direction register allowing each I/O bit
to be individually programmed as input or output. At reset, this port is
set to input mode. The output structure is N-channel open-drain output.
The note out of this Table gives a full of port P0 function.
