Timebase timer
21-bit
Four interrupt intervals selectable 0.82 ms, 3.3 ms, 26.2 ms, or 419.4 ms (approx.) (for
main clock)
Watchdog timer
Reset trigger period : 419.4 ms (10 MHz main clock)
500 ms (32.768 MHz sub-clock)
I2C interface
One channel. Supports Intel SM bus (version 1.0) and Philips I2C bus standards.
Uses a 2-wire protocol for communications with other devices.
Included/Not included

ing. See “Ordering In-
formation” for details.)
Included
8/16-bit timer/
counter Timer
2 channel 8-bit timer/counter operation (independent operation clocks for timer 1 and
timer 2) or 16-bit timer/counter operation (operation clock period : 0.8
s to 204.8 s)
can execute an event counter operation and output a square wave using an external
Clock.
1 or 16-bit timer/counter operation mode
Serial I/O
8 bits
LSB-first or MSB-first selectable
Transfer clocks : External or three internal clocks (0.8
s, 3.2 s, 12.8 s)
External
interrupt 1
(edge)
Selectable edge detection (rising, falling, or either edge)
3 independent channels
These can also be used to recover from standby modes (edge detection is still available
in stop mode) .
External
interrupt 2
(level)
1 channel with 8 inputs (“L” level interrupts, independent input enable)
This can also be used to recover from standby modes (level detection is still available in
stop mode) .
