Description

General PWM Timer

(GPT)

[RZ/G2L]

● 32 bits × 8 channels

[RZ/G2LC]

● 32 bits × 6 channels

[RZ/G2L RZ/G2LC]

● Counting up or down (sawtooth wave), counting up and down (triangular wave) selectable for

all channels

● Independent selectable for each channel

● 2 input/output pins per channel

● 2 output compare / input capture registers per channel

● For the 2 output compare / input capture registers of each channel, 4 registers are provided as

buffer registers and are capable of operating as comparison registers when buffering is not in

use

● In output compare operation, buffer switching can be at peaks or troughs, enabling the

generation of laterally asymmetrically PWM waveforms

● Registers for setting up frame intervals on each channel (with capability for generating

interrupts on overflow or underflow)

● Generation of dead times in PWM operation

● Synchronous start / stop / clear of counters on arbitrary channels

● Starting, stopping, and clearing up/down counters in response to a maximum of eight events

● Starting, stopping, and clearing up/down counters in response to input level comparison

● Starting, stopping, and clearing up/down counters in response to a maximum of four external

triggers

● Output pin invalidation functions due to dead time error or detection of short circuit between

output pins

● Digital filter functions for the input capture and external trigger pins

Port Output Enable for GPT

(POEG)

[RZ/G2L RZ/G2LC]

● Output prohibition control of the GPT waveform output pin

● Activation with up to four input pins

● Activation by dead time error detection or output short detection

● Activation by register write

Watchdog Timer

(WDT)

[RZ/G2L RZ/G2LC]

● 3 channels

● A counter overflow can reset the LSI

● CPU parity error can reset the LSI

General Timer

(GTM)

[RZ/G2L RZ/G2LC]

● 32 bits × 3 channels

● Two operating modes

– Interval timer mode

– Free-running comparison mode
