motor or be used for power management applications. The general level3 timer has a 16-bit

counter that can be used as an unsigned counter.

The general level4 timer module (TIMER15/16) is a two-channel timer that supports both input

capture and output compare. They can generate PWM signals to control motor or be used for

power management applications. The general level4 timer has a 16-bit counter that can be

used as an unsigned counter.

The basic timer module(TIMER5/6/50/51) has a 32-bit or 64-bit counter that can be used as

an unsigned counter. The basic timer can be configured to generate a DMA request and a

TRGO0 to connect to DAC.

The GD32H757xx have two watchdog peripherals, free watchdog timer and window watchdog

timer. They offer a combination of high safety level, flexibility of use and timing accuracy.

The free watchdog timer includes a 12-bit down-counting counter and an 8-bit prescaler. It is

clocked from an independent 32 KHz internal RC and as it operates independently of the

main clock, it can operate in deep-sleep and standby modes. It can be used either as a

watchdog to reset the device when a problem occurs, or as a free-running timer for application

timeout management.

The window watchdog timer is based on a 7-bit down counter that can be set as free-running.

It can be used as a watchdog to reset the device when a problem occurs. It is clocked from

the main clock. It has an early wakeup interrupt capability and the counter can be frozen in

debug mode.

The SysTick timer is dedicated for OS, but could also be used as a standard down counter. It

features:



A 24-bit down counter.



Auto reload capability.



Maskable system interrupt generation when the counter reaches 0.



Programmable clock source.

3.21.

Universal synchronous/asynchronous receiver transmitter

(USART/UART)



Programmable baud-rate generator allowing speed up to 37.5 MBits/s when the clock

frequency is 300 MHz and oversampling is by 8.



Supports both asynchronous and clocked synchronous serial communication modes



IrDA SIR encoder and decoder support.



LIN break generation and detection.



ISO 7816-3 compliant smart card interface.

The USART (USART0, USART1, USART2, USART5) and UART (UART3, UART4, UART6,

UART7) are used to transfer data between parallel and serial interfaces, provides a flexible

full duplex data exchange using synchronous or asynchronous transfer. It is also commonly
