Abstract

The timer module (TIMx) is a timer counting module with multiple compare/capture blocks. Based on the device, two types of timers are available: general-purpose timers (TIMG) and advanced control timers (TIMA). Both timers use a common timer architecture, which allows for easy migration between timer instances with common functions. This minimizes the need to write extra software for timer-based applications and allows for easy porting and maintenance between TIMx instances.

The TIMA module consists of a 16-bit auto reload counter driven by a programmable prescaler with up to four capture/compare (CC) blocks for multiple capture/compares, PWM outputs with deadband insertion, and interval timing. TIMA has extensive event generation capabilities from different counter events such as overflow, reload, and from each of the capture/compare registers. It also has the hardware design to handle the fault signal generated by internal or external circuitry to indicate a fault in the system.

Based on TIMA, you can configure richer timer module behaviors to design and implement more complex applications, such as motor control, LED modules, power modules, etc. Advanced control timers help you achieve better control and better digital outputs.
