REFERENCE MANUAL
The rate at which TCR1 is incremented is determined as follows:
Figure 8-2
• The PSCK and TCR1P fields in TPUMCR
• The DIV2 field in TPUMCR2
• The EPSCKE and EPSCK fields in TPUMCR3.
• The user selects either the standard prescaler (by clearing the enhanced prescal-
er enable bit, EPSCKE, in TPUMCR3) or the enhanced prescaler (by setting
EPSCKE).
— If the standard prescaler is selected (EPSCKE = 0), the the PSCK bit deter-
— If the enhanced prescaler is selected (EPSCKE = 1), the EPSCK bits select a

output of the TCR1 prescaler (which, in turn, takes as input the output of either
the standard or enhanced prescaler).
