The Quadrature Position/Revolution Counter (QPRC) is used to measure the position of the position

encoder. Moreover, it is possible to use up/down counter.

・

The detection edge of the three external event input pins AIN, BIN and ZIN is configurable.

・

16-bit position counter

・

16-bit revolution counter

・

Two 16-bit compare registers



Dual Timer (Two 32/16bit Down Counter)

The Dual Timer consists of two programmable 32/16-bit down counters.

Operation mode is selectable from the followings for each channel.

・

Free-running

・

Periodic (=Reload)

・

One-shot



Watch Counter

The Watch counter is used for wake up from power saving mode.

・

Interval timer: up to 64s(Max.)@ Sub Clock : 32.768kHz



External Interrupt Controller Unit

・

Up to 16 external vectors

・

Include one non-maskable interrupt(NMI)



Watch dog Timer (2channels)

A watchdog timer can generate interrupts or a reset when a time-out value is reached.

MB9B100 series consists of two different watchdogs, a "Hardware" watchdog and a "Software" watchdog.

"Hardware" watchdog timer is clocked by low speed CR oscillator. Therefore,”Hardware" watchdog is

active in any power saving mode except STOP.
