TCR1P — Timer Count Register 1 Prescaler Control
TCR1 is clocked from the output of a prescaler. The prescaler's input is the internal TPU system clock
divided by either 4 or 32, depending on the value of the PSCK bit. The prescaler divides this input by 1,
2, 4, or 8. Channels using TCR1 have the capability to resolve down to the TPU system clock divided
by 4.
TCR2P — Timer Count Register 2 Prescaler Control
TCR2 is clocked from the output of a prescaler. If T2CG = 0, the input to the TCR2 prescaler is the ex-
ternal TCR2 clock source. If T2CG = 1, the input is the TPU system clock divided by eight. The TCR2P
field specifies the value of the prescaler: 1, 2, 4, or 8. Channels using TCR2 have the capability to re-
solve down to the TPU system clock divided by 8. The following table is a summary of prescaler output.
