P : period register (initial counter value)

T : count-down register (counts from the value in P) 0x0000 : default state of both registers after RESET LOW

²TIMER1 may be associated with the comparator function, if the comparator enable bit is set. Refer to Section 3.3, Comparator, for details.

Reading from either the PRD or the TIM returns the current state of the register. This can be used to monitor the progress of the TIM register at any time.

Writing to the PRD register does not change the TIM register until the TIM register has finished decrementing to 0x0000. The new value in the PRD register is then loaded to the TIM register, and counting resumes from the new value.

Note: Writing to the TIM Register

Writing to the TIM register causes the same value to be written to the PRD register. In this case, the TIM register is immediately updated, and counting continues immediately from the new value.

Each TIMER decrements its count-down register at a fixed clock rate. The rate is selectable between two existing clock sources: the reference oscillator or 1/2 Master Clock. The rate of the master clock (MC) is programmable. It is determined by the value loaded to the PLL multiplier (Section 2.9.3, Clock Speed Control Register). The source to the TIMER is therefore one-half the frequency of the programmed master clock (1/2 MC). If, instead, the reference oscillator is selected as the source to the TIMER, then the source is either a resistor-trimmed oscillator (RTO) or a crystal oscillator (CRO). Both reference oscillators are designed to run at a nominal 32 kHz. Refer to Section 2.9, Clock Control, for more information regarding the oscillator configuration and clock programmability.
