Prescaler write-once disable bit. The PWOD bit does not lock the EPSCK field and the EPSCKE
bit.
0 = Prescaler fields in MCR are write-once
1 = Prescaler fields in MCR can be written anytime
TCR2 prescaler 2
0 = Prescaler clock source is divided by one.
1 = Prescaler clock is divided. See divider definitions in
Enhanced pre-scaler enable
0 = Disable enhanced prescaler (use standard prescaler)
1 = Enable enhanced prescaler. IMB clock will be divided by the value in EPSCK field.
