Product List
This functional diagram shows Timer 1 operating as a 16 bit timer with auto reload. The timer operates in an up counting mode with the overflow value equal to 0xFFFF. The timer run control bit (TR1) is used to start the timer and is set using the TMR1CN register at address 0x59. The Timer 1 Control register (TMR1CN) also determines the clock input that drives the timer which can be the system clock divided by 12 or the smaRTClock oscillator divided by 8. Timer 1 can also operate in a capture mode as a means to calibrate the smaRTClock oscillator with the selected system clock.
