9. Module: PFM Self Writes

9.1 PFM

Writes to the PFM will not execute if the device’s

clock source is HS, ECH, or the Internal Oscillator

is at either 8 MHz or 16 MHz. The DFM is

unaffected.

Work around

To write to the PFM, the clock source must be one

of the following settings: Internal Oscillator set to 4

MHz or lower, ECM, ECL, XT, External RC, LP or

T1OSC.
