Timer A

Timer_A Introduction

Timer_A is a 16-bit timer/counter with three capture/compare registers. Timer_A can support multiple capture/compares, PWM outputs, and interval timing. Timer_A also has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers.

Timer_A features

• Asynchronous 16-bit timer/counter with four operating modes

• Selectable and configurable clock source

• Two or three configurable capture/compare registers

• Configurable outputs with PWM capability

• Asynchronous input and output latching

• Interrupt vector register for fast decoding of all Timer_A interrupts
