PIN DESCRIPTION
Pin
Functions
Apply voltage of 5 V ± 10 % (typical) to V
CC
and AV
CC
, and 0 V to V
SS
.
Connected to V
SS
.
To enter the reset state, the reset input pin must be kept at a “L” for 2
m
s or more (under
normal V
CC
conditions).
If more time is needed for the quartz-crystal oscillator to stabilize, this “L” condition should
be maintained for the required time.
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
IN
and
X
OUT
. If an external clock is used, the clock source should be connected to the X
IN
pin and
the X
OUT
pin should be left open.
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 CMOS output. See notes at end of table for full details of port P0 functions.
Port P1 is an 8-bit I/O port and has basically the same functions as port P0. The output
structure is CMOS output.
Port P2 is an 8-bit I/O port and has basically the same functions as port P0. The output
structure is CMOS output.
