Dedicated output ports P80 to P83
Output in 4-bit or 1-bit units
The contents of the output latch are
input using input instructions.
P80 is a data shaper input (options)
P81 is a data shaper output (options)
I/O ports PC0 to PC3
Output in 4-bit or 1-bit units
Dedicated inverter circuits (option)
Used as the control CE and DASEC
pin in EPROM mode.
Dedicated input ports PD0 to PD3
Can be switched in software to function
as 16-value analog inputs.
Dedicated inverter circuits (option)
Dedicated input ports and sub-oscillator
connections
System clock oscillator connections
When an external clock is used, leave
OSC2 open and connect the clock signal
to OSC1.
System reset input
When the P33/HOLD pin is at the high
level, a low level input to the RES pin
will initialize the CPU.
Used as the VPP/OE pin in EPROM
mode.
CPU test pin
This pin must be connected to V
SS
during normal operation.
