(may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a prescaler, a base timer serving as a
time-of-day clock, a high-speed clock counter, a synchronous SIO interface (with automatic block transmission/reception
capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), an 8-bit 11-channel AD
converter, two 12-bit PWM channels, a system clock frequency divider, ROM correction function , and a 23-source
10-vector interrupt feature.

Interrupts
•
23 sources, 10 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.

Standby Function
•
HALT mode : Halts instruction execution while allowing the peripheral circuits to continue operation.
1) Oscillation is not halted automatically.
2) Canceled by a system reset or 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 three ways of resetting the HOLD mode.
(1) Setting the reset pin to the lower level
(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
(3) Having an interrupt source established at port 0
•
X'tal HOLD mode : Suspends instruction execution and the operation of the peripheral circuits except the
base timer.
1) The CF and RC oscillators automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are four ways of resetting the X'tal HOLD mode.

(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
(3) Having an interrupt source established at port 0
(4) Having an interrupt source established in the base timer circuit
