(4) Input / Output Terminals
- Input ports
: 4 terminals (S-port : 4 terminals)
- Input / Output ports : 8 terminals (P0 port : 4 terminals, P1 port : 4 terminals)
[Notes] When using the P1 port for output, the “L” level hold Tr. of P1 should be OFF.
If P1 port becomes “H” level with “L” level hold Tr. on, it causes the through current from VDD to GND
and increases the current consumption.
- Output ports
: 2 terminals (Buzzer / melody output terminal : 1 terminal,
General output port : 1 terminal)
- LCD segment output ports
: 32 terminals (Possible to use output port by mask option)
- LCD common output ports
: 4 terminals

Note:
When a Lithium battery has been selected as the power supply, please note the following points.
There are two modes of use for the lithium battery: Backup mode and Normal mode (backup flag off). In backup mode, the
battery potential is applied directly to the oscillation circuit, whereas in Normal mode only half the battery potential is applied.
Because of the different voltage applied to the oscillation circuit in each mode, there may be a difference in the generated
oscillation frequency. When entering backup mode a corresponding error will arise. If timing accuracy is required (for clocks,
etc), please bear in mind the above in the program design.

Note 1)
If P0, P1 port or segment output (SEG17 to SEG32) are used for key scan output port, P-ch open drain option should
be used in order to prohibit signal short between output ports when two or more keys are pushed simultaneously.
Note 2)
If P1 port is used as output port, the following setting is necessary. Programmable pull-down resistors which is one
of the internal pull-down register should be set to open mode with the SPDR instruction.

The specifications above are for a die mounted in a QFP64 type package. The specifications for a die is almost same as ones for
a QFP type package basically. However, the operational characteristics may vary depending on the user’s assembling method.
Therefore, the operating temperature range for a die is specified only in Ta=25°C±2°C.
