Safe Calibration. This bit facilitates the use of safety-critical calibration data. When this bit
is enabled, the flash memory controller is configured to perform redundancy checking on
the calibration remap function and reduce the total number of potential calibration regions
from 32 to 16. This field is initialized by hardware reset.
0 Established calibration overlay regions are considered safety-critical.
1 Established calibration overlay regions are not considered safety-critical.
Instruction Remap. This bit enables calibration remapping evaluation on instruction fetches.
When PFCRCR[GRMEN] is disabled, this bit is ignored.
This field is initialized by hardware reset.
0 Calibration remap evaluation is performed on any incoming data fetch requests only.
1 Calibration remap evaluation is performed on all incoming flash access requests - data
and instruction fetches.
Global Remap Enable. This bit globally enables or disables the calibration remapping
evaluation on system flash accesses.
This field is initialized by hardware reset.
0 Calibration remap evaluation is not performed on any incoming system flash access
requests.
1 Calibration remap evaluation is performed on all incoming system flash access requests.
