If the operation is to erase a page of flash, the address specified in the 56800E program
memory write instruction must be any one of the addresses within the page to be erased.
If the operation is a mass erase, the address specified in the 56800E program memory
write instruction must be any one of the addresses within the data array. Data in the
56800E program memory write instruction is irrelevant for the erase to proceed.
20.3.4 Flash Commands
The following table summarizes the valid flash commands.

FM_CMD
1. Execute a 56800E program memory write instruction.
2. Write the erase command code (0040h or 0041h) to the command register.
3. Write 1 to the CBEIF bit to launch the erase process.

Signature
Meaning
Program
Verify that the flash array is erased. If the array is veri‐
fied to be blank, the BLANK bit sets in the USTAT reg‐
ister upon command completion.
Calculate a signature over user-specified range of
words in the flash array. The resulting signature is re‐
turned in the DATA register at the completion of the
command.
The new signature can be compared with a signature
previously calculated by the user to verify program
flash integrity.
Program a 16-bit word. Programming is only possible
when the protection bit for the applicable sector is not
set.
Erase a specific page (sector) of the flash array. A
page erase is possible only when the PROTECT bit for
the selected page is not set.
Erase all flash memory. A mass erase is possible only
when no PROTECT bits are set.

Preliminary
The address must be any address
within the array. Data is ignored.
The array write address specifies
the starting address and data speci‐
fies the number of words to com‐
press.
The address and data specify the
address and value to program.
The address must be any address
within the page to be erased. Data
is ignored.
The address must be any address
within the array. Data is ignored.
