12 Timer 1 16-bit Timer Mode: In the 16-bit Timer mode, the timer increments on every instruction cycle up to a match value, preloaded into the Period register, PR1, then resets to 0 and continues to count. When the CPU goes into the Idle mode, the timer will stop incrementing unless the TSIDL (T1CON ) bit 0. If TSIDL 1, the timer module logic will resume the incrementing sequence upon termination of the CPU Idle mode. 16-bit Synchronous Counter Mode: In the 16-bit Synchronous Counter mode, the timer increments on the rising edge of the applied external clock signal, which is synchronized with the internal phase clocks. The timer counts up to a match value preloaded in PR1, then resets to 0 and continues. When the CPU goes into the Idle mode, the timer will stop incrementing unless the respective TSIDL bit o. If TSIDL 1, the timer module logic will resume the incrementing sequence upon termination of the CPU Idle mode.
