Interrupt
Occurs when “0” is specified as the divisor for the DIV instruction (Division instruction).
(Refer to “7700 Family Software Manual.”)
Occurs when the BRK instruction is executed.
(Refer to “7700 Family Software Manual.”)
Occurs when the most significant bit of the watchdog timer becomes “0.”
(Refer to “Chapter 9. WATCHDOG TIMER.”)
Differs according to the timer Ai’s operating modes.
(Refer to “Chapter 5. TIMER A.”)
Differs according to the timer Bi’s operating modes.
(Refer to “Chapter 6. TIMER B.”)
Occurs at serial data reception. (Refer to “Chapter 7. SERIAL I/O.”)
Occurs at serial data transmission. (Refer to “Chapter 7. SERIAL I/O.”)
Occurs when A-D conversion is completed. (Refer to “Chapter 8. A-D CONVERTER.”)
