Figure 7-48. Precision Timer Modulus Counter Prescaler Select Register (PTMCPSR)
Precision Timer Modulus Counter Prescaler Select Bits — These eight bits specify the division rate of the
modulus counter prescaler. These are effective only when the PRNT bit of TSCR1 is set to 1.
some possible division rates.
The newly selected prescaler division rate will not be effective until a load of the load register into the modulus
counter count register occurs.
