The F1680 devices contain three 16-Bit reloadable timers with noise filters that are used for timing, event count, or generation of dual Pulse-Width Modulation (PWM) signals. These timers feature a 16 bit reload counter, programmable prescaler with values ranging from 1 to 128, and PWM output generation. It also features two independent capture/compare channels that reference the common timer, an external input pin for timer input, clock gating, capture signal, timer output pin and timer interrupt, and operation in any mode with 32 kHz secondary oscillator. This device can be used for a software RTC and has the ability to cascade all three timers to be one 48-bit timer.
