8/16-bit timer

counter

8/16-bit timer operation (Operating clock, internal clock, external trigger)

8/16-bit event counter operation (Rising edge/falling edge/both edges selectability)

8-bit Serial I/O

8 bits

LSB first/MSB first selectability

One clock selectable from four transfer clocks

(one external shift clock, three internal shift clocks: 4, 8, 16 system clock cycles)

A/D converter

8-bit resolution

× 8 channels

A/D conversion mode (with

conversion time of 22

µs/8 MHz,

and highest gear speed)

Continuous activation by external

activation cabable

10-bit resolution

× 12 channels

A/D conversion mode (with conversion time of 16.5 ms/

8 MHz, and highest gear speed)

Sense mode (with conversion time of 9.0

µs/8 MHz,

and highest gear speed)

Continuous activation enabled by external activation capable

External interrupt

2 independent channels (edge selection, interrupt vector, source flag)

Rising edge/falling edge/both edges selectability

Built-in analog noise canceller

Used also for wake-up from stop/sleep mode. (Edge detection is also permitted in stop mode.)

Buzzer output

1.95 or 3.91 kHz selectable (at 8-MHz oscillation)

Output to a high-voltage pin
