8-bit Proprietary Microcontroller

Fujitsu 

MB89810A Series

(Continued)

• External interrupt: 8 channels

Eight channels are independent and capable of wake-up from low-power consumption modes (with an edge

detection function).

• Low-power consumption modes

Stop mode (Oscillation stops to minimize the current consumption)

Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal)

LSB-first/MSB first selectability

One clock selectable from four transfer clocks

(one external shift clock, three internal shift clocks)

External interrupt

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

4 channels: Level detection (level selectable)

4 channels: Edge detection (edge selectable)

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