The data sheet FTS512K4 for the MC9S12Dx512 describes FPHS[1:0] and FPLS[1:0] but don't explicitly say they don't mean anything if FPHDIS and FPLDIS are set to 1 (Protection disabled). I'm assuming they are ignored. Can anyone confirm? Thanks
It's true it isn't explicitly described, but we can logically understand from the FPROT register description that
FPHDIS and FPHS[1:0] are in relation with each other as well as FPLDIS and FPLS[1:0].
As it is written:
If the FPOPEN bit is cleared, then the state of the FPHDIS, FPHS[1:0], FPLDIS and FPLS[1:0] bits is irrelevant.
