UNUSED. Read = 00000b, Write = don't care.
SFLE: Scratchpad Flash Memory Access Enable
When this bit is set, Flash reads and writes from user software are directed to the 128-byte
Scratchpad Flash sector. When SFLE is set to logic 1, Flash accesses out of the address
range 0x00-0x7F should not be attempted. Reads/Writes out of this range will yield unde-
fined results.
0: Flash access from user software directed to the Program/Data Flash sector.
1: Flash access from user software directed to the 128 byte Scratchpad sector.
PSEE: Program Store Erase Enable.
Setting this bit allows an entire page of the Flash program memory to be erased provided
the PSWE bit is also set. After setting this bit, a write to Flash memory using the MOVX
instruction will erase the entire page that contains the location addressed by the MOVX
instruction. The value of the data byte written does not matter. Note: The Flash page con-
taining the Read Lock Byte and Write/Erase Lock Bytes cannot be erased by soft-
ware.
0: Flash program memory erasure disabled.
1: Flash program memory erasure enabled.
PSWE: Program Store Write Enable.
Setting this bit allows writing a byte of data to the Flash program memory using the MOVX
write instruction. The location must be erased prior to writing data.
0: Write to Flash program memory disabled. MOVX write operations target External RAM.
1: Write to Flash program memory enabled. MOVX write operations target Flash memory.
