User Option Types
1. Port 0, 1 and 8 reset time output level option
The output levels of I/O ports 0, 1 and 8 at reset can be selected from the following two options in 4-bit units.
2. Oscillator circuit option
Note: There is no RC oscillator option.
3. Watchdog timer option
The presence or absence of a program runaway detection function (watchdog timer) can be selected as an option.

Dedicated input port
Can be switched under software
control to function as a three-
value input port.
System clock oscillator connections
When an external clock is used,
leave OSC2 open and input the
signal to OSC1.
System reset input
The CPU is initialized (reset) if a
low level is input to RES when
P33/HOLD is at the high level.
CPU testing
This pin must be connected to
V
SS
during normal operation.
Power supply connections
Selection of either a
ceramic oscillator or
external clock input
Option
Conditions and notes
High level output at reset time
Ports 0, 1 and/or 8 in 4-bit sets
Low level output at reset time
Ports 0, 1 and/or 8 in 4-bit sets
Option
Circuit
Conditions and notes
External clock
Ceramic oscillator
This input is a Schmitt specification input.
