Timer and Modulus Counter Stop While in Freeze Mode
0 Allows the timer and modulus counter to continue running while in freeze mode.
1 Disables the timer and modulus counter whenever the MCU is in freeze mode. This is useful for emulation.
Timer Fast Flag Clear All
0 Allows the timer flag clearing to function normally.
1 A read from an input capture or a write to the output compare channel registers causes the corresponding

in the TFLG2 register. Any access to the PACN3 and PACN2 registers clears the PAOVF and PAIF flags in the
PAFLG register. Any access to the PACN1 and PACN0 registers clears the PBOVF flag in the PBFLG register.
Any access to the MCCNT register clears the MCZF flag in the MCFLG register. This has the advantage of
eliminating software overhead in a separate clear sequence. Extra care is required to avoid accidental flag
clearing due to unintended accesses.
