not, all four bytes of the instruction must be transmitted. If the 0x53 did not echo
back, give RSTN a positive pulse and issue a new Programming Enable command.
4. The Flash is programmed one page at a time. The memory page is loaded one byte
at a time by supplying the 7 LSB of the address and data together with the Load
Program Memory Page instruction. To ensure correct loading of the page, the data
low byte must be loaded before data high byte is applied for a given address. The
Program Memory Page is stored by loading the Write Program Memory Page
instruction with the address lines 15:8. If polling (RDY/BSY¯ ¯ ¯ ) is not used, the user
must wait at least t
WD_FLASH
before issuing the next page (see Table 31-16 below).
Accessing the serial programming interface before the Flash write operation
completes can result in incorrect programming.
5. The EEPROM array is programmed one byte at a time by supplying the address and
data together with the appropriate Write instruction. An EEPROM memory location is
first automatically erased before new data is written. If polling is not used, the user
must wait at least t
WD_EEPROM
before issuing the next byte (see Table 31-16 below).
In a chip erased device, no 0xFFs in the data file(s) need to be programmed.
6. Any memory location can be verified by using the Read instruction which returns the
content at the selected address at serial output PDO.
7. At the end of the programming session, RSTN can be set high to commence normal
operation.
8. Power-off sequence (if needed): Set RESET to “1”. Turn DEVDD power off.
