3.12.6 Flash memory read wait-state and address-pipeline control
settings
The following table describes the recommended settings of the Flash Memory
Controller's PFCR1[RWSC] and PFCR1[APC] fields at various flash memory operating
frequencies, based on specified intrinsic flash memory access times of the C55FMC array
at 150°C.
