No. 5582-3/19
(10) Remote control receiver circuit (shares with the P73/INT3/T0IN pin)
- Noise rejection function
- Polarity switching
(11) Watchdog timer
External RC circuit is required
Interrupt or system reset is selectable.
(12) Interrupts
- 12-source 9-vectored interrupts
1. External interrupt INT0
2. External interrupt INT1
3. External interrupt INT2, Timer/counter T0L (Lower 8 bits)
4. External interrupt INT3
5. Timer/counter T0H (Upper 8 bits)
6. Timer T1H, T1L
7. Serial interface 0 (SIO0)
8. Vertical synchronous signal interrupt (VS) , End of display row
9. Port 0
- Interrupt priority control available
Three interrupt priorities are supported (low, high and the highest) and multilevel nesting is possible. Low or high priority
can be assigned to the interrupts from 3 to 10 listed above. For the external interrupt INT0 and INT1, high or the highest
priority can be set.
(13) Sub-routine stack level
- A maximum of 128 levels (Sets the stack inside a RAM.)
(14) Multiplication/division instruction
- 16 bits
× 8 bits ( 7 instruction cycle times)
- 16 bits / 8 bits ( 7 instruction cycle times)
(15) 3 oscillation circuits
- On-chip RC oscillation circuit for the system clock
- On-chip CF oscillation circuit for the system clock
- On-chip LC oscillation circuit for the CRT synchronization
(16) Standby function
- HALT mode function
The HALT mode is used to reduce the power dissipation. In this operation mode, the program execution is stopped. This
mode can be released by the interrupt request signals or the system reset.
- HOLD Mode
The HOLD mode is used to stop oscillations ; the RC (internal) and the ceramic oscillations. This mode can be released by
the following conditions.
Pull the reset pin (RES) to low level.
Feed the selected level to either P70/INT0 or P71/INT1.
Feed the Port0 interrupt condition.
(17) Factory shipments
DIP52S
