Timer/ Event Counter
Timer/Event Counter Programming Model
The PS[1:0] bits are cleared by the hardware RESET signal or the software RESET
instruction.
Note:
To ensure proper operation, change the PS[1:0] bits only when the prescaler
counter is disabled. Disable the prescaler counter by clearing the TE bit in the
TCSR of each of three timers.
13.3.2.3
TPLR Reserved Bit 23
This reserved bit is read as zero and should be written with zero for future compatibility.
13.3.3
TIMER PRESCALER COUNT REGISTER (TPCR)
The TPCR is a 24-bit read-only register that reflects the current value in the prescaler counter.
See Figure 13-5.
13.3.3.1
TPCR Prescaler Counter Value PC[20:0] Bits 20–0
These 21 bits contain the current value of the prescaler counter.
13.3.3.2
TPCR Reserved Bits 23–21
These reserved bits are read as zero and should be written with zero for future compatibility.
