by the upper 5 bits of the 6th bus write cycle address. The range of addresses that can be specified is shown in
Table 21-3. For example, to erase Block1 (2 kbytes from 0x8000 through 0x87FF in the code area), set
FLSCR1<FAREA> to "0y10", set "0xD5" on FLSCR2<CR1EN>, and then specify either 0x8000 or 0x87FF as
the 6th bus write cycle. The sector erase command is effective only in MCU and serial PROM modes, and it
cannot be used in parallel PROM mode.
an ongoing erase operation is not completed. To check the completion of the erase operation, perform read
operations twice on the same address in the flash memory, and perform polling until the same data is read from
the flash memory. During the erase operation, bit 6 is reversed each time a read is performed.
no matter how the Security program setting. In case of Sector Erase for the protected area where the protect is
on, Flash memory ignore the the write command ( to prevent un intentional writing, like miss operation.) There
is the function to be able to rewrite the data for these area in TMP89FM82T. Refer to "21.2.6 Protect cancel mode
(FLSVPR<VPREG>)" "21.2.7 Protect set up".
Table 21-3 Range of Addresses Specifiable
Note 1: The data and code areas become mirror areas. As you access these areas, you are brought to the same
Note 2: Do not perform a sector erase on areas other than those shown in Table 21-3.
This command erases the flash memory in units of 2, 4, 8 kbytes. The flash memory area to be erased is specified
The time needed to erase each Block is maximum 40 ms. The next commnd sequence cannot be executed if
Data in the erased area is 0xFF.
In case of MCU mode, only Block0 and Block1 is able to write data. Block2 to Block6 is not able to wite data,
