Cache Prefect Enable Bit.
0: Prefetch engine is disabled.
1: Prefetch engine is enabled.
Must Write 0000b.
Block Write Enable Bit.
This bit allows block writes to Flash memory from firmware.
0: Each byte of a software Flash write is written individually.
1: Flash bytes are written in groups of two.
Reserved
Read = 0000b. Write = don’t care.
These bits limit the internal Flash read strobe width as follows. When the Flash read
strobe is de-asserted, the Flash memory enters a low-power state for the remainder
of the system clock cycle. These bits have no effect when the system clocks is
greater than 12.5 MHz and FLRT = 0.
