Input/Output
Supply 5 V ±10 % to Vcc pin and 0 V to Vss pin.
This pin controls the processor mode.
[Single-chip mode] [Memory expansion mode]
Connect to Vss pin.
[Microprocessor mode]
Connect to Vcc pin.
The microcomputer is reset when supplying “L” level
to this pin.
These are I/O pins of the internal clock generating
circuit. Connect a ceramic resonator or quartz-crystal
oscillator between pins X
external clock, the clock source should be input to X
pin and X
This pin outputs E signal.
Data/instruction code read or data write is performed
when output from this pin is “L” level.
[Single-chip mode]
Connect to Vss.
[Memory expansion mode] [Microprocessor mode]
Input level to this pin determines whether the external
data bus has a 16-bit width or 8-bit width. The width
is 16 bits when the level is “L”, and 8 bits when the
level is “H”.
The power supply pin for the A-D converter. Externally
connect AVcc to Vcc pin.
The power supply pin for the A-D converter. Externally
connect AVss to Vss pin.
This is a reference voltage input pin for the A-D converter.
OUT
pin should be left open.
