19. Flash Memory
19.2 Command Sequence
T
5CL8
A maximum of 30 ms is required to erase 4 kbytes. The next command sequence cannot be executed until the
erase operation is completed. To check the completion of the erase operation, perform read operations repeat-
edly for data polling until the same data is read twice from the same address in the flash memory. During the
erase operation, any consecutive attempts to read from the same address is reversed bit 6 of the data (toggling
between 0 and 1).
19.2.3 Chip Erase (All Erase)
This command erases the entire flash memory in approximately 30 ms. The next command sequence cannot
be executed until the erase operation is completed. To check the completion of the erase operation, perform
read operations repeatedly for data polling until the same data is read twice from the same address in the flash
memory. During the erase operation, any consecutive attempts to read from the same address is reversed bit 6
of the data (toggling between 0 and 1). After the chip is erased, all bytes contain FFH.
19.2.4 Product ID Entry
This command activates the Product ID mode. In the Product ID mode, the vendor ID, the flash ID, and the
security program status can be read from the flash memory.
Note: The value at address F002H (flash size) depends on the size of flash memory incorporated in each product. For example, if
the product has 60-kbyte flash memory, "0EH" is read from address F002H.
19.2.5 Product ID Exit
This command is used to exit the Product ID mode.
19.2.6 Security Program
This command enables the read protection or write protection setting in the flash memory. When the security
program is enabled, the flash memory cannot be read in the parallel PROM mode. In the serial PROM mode,
the flash write and RAM loader commands cannot be executed.
To enable the security program setting in the serial PROM mode, set FLSCR<BANKSEL> to "1" before
executing the security program command sequence. To disable the security program setting, it is necessary to
execute the chip erase command sequence. Whether or not the security program is enabled can be checked by
reading FF7FH in the Product ID mode. For details, see Table 19-4.
