The use of PSCnRB fuse can make the parallel ISP fail.
Workaround:
When PSCnRB fuses are used, use the serial programming mode to load a new program
version.
The use of PSC's prescaler have the following effects :
It blocks the sample of PSC inputs until the two first cycles following the set of PSC run bit.
A fault is not properly transferred to other (slave) PSC.
Workaround:
Clear the prescaler PPREx bit when stopping the PSC (prun = 0), and set them to appropri-
ate value when starting the PSC (prun = 1), these bits are in the same PCTL register
Do not use the prescaler when a fault on one PSC should affect other PSC’s
These register bits are malfunctioning.
Workaround:
Do not use this feature.
These flags are set when a fault arises, but can also be set again during the fault itself.
Workaround:
Don't clear these flags before the fault disappears.
