is loaded with valid data from the D-Flash EEE partition. Completion of this phase is indicated by the
CCIF flag in the FTM FSTAT register becoming set. If the CPU accesses any EEE RAM location before
the CCIF flag is set, the CPU is stalled until the FTM reset sequence is complete and the EEE RAM data
is valid. Once the CCIF flag is set, indicating the end of this phase, the EEE RAM can be accessed without
impacting the CPU and FTM commands can be executed.
1.6.3.3
If a reset occurs while any Flash command is in progress, that command will be immediately aborted. The
state of the word being programmed or the sector/block being erased is not guaranteed.
1.6.3.4
Refer to the PIM block description for reset configurations of all peripheral module ports.
1.6.3.5
The RAM arrays are not initialized out of reset.
1.6.3.6
The COP timeout rate bits CR[2:0] and the WCOP bit in the COPCTL register are loaded on rising edge
of RESET from the Flash register FOPT. See
loaded from the Flash configuration field byte at global address $7FFF0E during the reset sequence.
If the MCU is secured the COP timeout rate is always set to the longest period (CR[2:0] = 111) after COP
reset.
