Timer Controller (TMR)

6.7.1

Overview

The Timer controller contains four 32-bit multi-functional timers, Timer0, 1, 2 and 3. These timers
can be used to count, or time external events that drive the Timer input pins.
Or the four timers can be configured as four PWM generators; each can support two PWM output
channels in independent or complementary mode. The output state of PWM output pin can be
control by pin mask, polarity, and dead-time generator.

Features

6.7.2.1 Timer Function Features

Four sets of 32-bit timers, each timer equips one 24-bit up counter and one 8-bit prescaler
counter

Independent clock source for each timer

Provides one-shot, periodic, toggle-output and continuous counting operation modes

24-bit up counter value is readable through CNT (TIMERx_CNT[23:0])

Supports event counting function

24-bit capture value is readable through CAPDAT (TIMERx_CAP[23:0])

Supports external capture pin event for interval measurement

Supports external capture pin event to reset 24-bit up counter

Supports chip wake-up from Idle/Power-down mode if a timer interrupt signal is generated

Support Timer0 ~ Timer3 time-out interrupt signal or capture interrupt signal to trigger PWM,
EADC and PDMA function

Supports Inter-Timer trigger mode
6.7.2.2 PWM Function Features

Supports maximum clock frequency up to maximum PCLK

Supports independent mode for PWM generator with two output channels

Supports complementary mode for PWM generator with paired PWM output channel

12-bit dead-time insertion with 12-bit prescaler

Supports 12-bit prescaler from 1 to 4096

Supports 16-bit PWM counter

Up, down and up-down count operation type

One-shot or auto-reload counter operation mode

Supports mask function and tri-state enable for each PWM output pin

Supports interrupt on the following events:

PWM zero point, period point, up-count compared or down-count compared point
events

Supports trigger ADC on the following events:
