(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
