Feature

Description

8-bit timer,

4 channels

• 8-bit up-counter (external event count capability)

• Two time constant registers

• Two channels can be connected

Programmable

timing pattern

controller (TPC)

• Maximum 16-bit pulse output, using 16-bit timer as time base

• Up to four 4-bit pulse output groups (or one 16-bit group, or two 8-bit groups)

• Non-overlap mode available

• Output data can be transferred by DMAC

Watchdog

timer (WDT),
