Serial data input
Serial data bus I/O
Edge detection vectored interrupt input
(valid for detecting both rising and falling edges)
Edge detection vectored interrupt input Noise elimination
(detected edge is selectable)
INT0/P10 can select noise elimination
circuit.
Rising edge detection test input
Parallel falling edge detection test input
Parallel falling edge detection test input
Ceramic/crystal oscillation circuit connection for main system
clock. If using an external clock, input to X1 and input
inverted phase to X2.
Crystal oscillation circuit connection for subsystem clock.
If using an external clock, input to XT1 and input inverted
phase to XT2. XT1 can be used as a 1-bit (test) input.
System reset input (low level active)
Mode selection for program memory (PROM) write/verify
Data bus for program memory (PROM) write/verify
Programmable power supply voltage for program memory
(PROM) write/verify.
For normal operation, connect to V
Apply +12.5 V for PROM write/verify.
Positive power supply
