The Prescaler can be calculated as follows depending on logical value of the PTPS[7:0] and PRNT bit:
PRNT = 1 : Prescaler = PTPS[7:0] + 1

Functional Description
Precision Timer Prescaler Select Bits — These eight bits specify the division rate of the main Timer prescaler.
These are effective only when the PRNT bit of TSCR1 is set to 1.
in this case.
The newly selected prescale factor will not take effect until the next synchronized edge where all prescale counter
stages equal zero.
