Interrupts
•
12 sources, 8 vector addresses
1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt requests of
the level equal to or lower than the current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level
takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.

Clock Divider Function
•
Can run on low current.
•

76.8μs (at a main clock rate of 10MHz).
Internal
reset function
•
Power-on reset (POR) function
1) POR reset is generated only at power-on time.
2) The POR release level can be selected from 8 levels (1.67V, 1.97V, 2.07V, 2.37V, 2.57V, 2.87V, 3.86V, and
4.35V) through option configuration.
•
Low-voltage detection reset (LVD) function
1) LVD and POR functions are combined to generate resets when power is turned on and when power voltage falls
below a certain level.
2) The use/disuse of the LVD function and the low voltage threshold level (7 levels: 1.91V, 2.01V, 2.31V, 2.51V,
2.81V, 3.79V, 4.28V).
Standby
Function
•
HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
1) Oscillation is not halted automatically.
2) There are three ways of resetting the HALT mode.
(1) Setting the reset pin to the low level
(2) System resetting by watchdog timer or low-voltage detection
(3) Occurrence of an interrupt
•
HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The CF, RC and crystal oscillators automatically stop operation.
2) There are four ways of resetting the HOLD mode.
(1) Setting the reset pin to the lower level.
(2) System resetting by watchdog timer or low-voltage detection
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4
* INT0 and INT1 HOLD mode reset is available only when level detection is set.
(4) Having an interrupt source established at port 0.
On-chip
Debugger
•
