31.7.2 Considerations for Efficient Programming
31.7.3 Chip Erase
31.7.4 Programming the Flash
8266B-MCU Wireless-03/11
The loaded command and address are retained in the device during programming. For
efficient programming, the following should be considered.
• The command needs only be loaded once when writing or reading multiple memory
• Skip writing the data value 0xFF, that is the contents of the entire EEPROM (unless
• Address high byte needs only be loaded before programming or reading a new 256
The Chip Erase will erase the Flash and EEPROM
Lock bits are not reset until the program memory has been completely erased. The
Fuse bits are not changed. A Chip Erase must be performed before the Flash and/or
EEPROM are reprogrammed.
Note:
Load Command “Chip Erase”
1. Set XA1, XA0 to “10”. This enables command loading.
2. Set BS1 to “0”.
3. Set DATA to “1000 0000”. This is the command for Chip Erase.
4. Give CLKI a positive pulse. This loads the command.
5. Give WR
6. Wait until RDY/BSY
The Flash is organized in pages; see
Flash, the program data is latched into a page buffer. This allows one page of program
data to be programmed simultaneously. The following procedure describes how to
program the entire Flash memory:
A. Load Command “Write Flash”
1. Set XA1, XA0 to “10”. This enables command loading.
2. Set BS1 to “0”.
3. Set DATA to “0001 0000”. This is the command for Write Flash.
4. Give CLKI a positive pulse. This loads the command.
B. Load Address Low byte (Address bits 7:0)
1. Set XA1, XA0 to “00”. This enables address loading.
2. Set BS2, BS1 to “00”. This selects the address low byte.
3. Set DATA = Address low byte (0x00 - 0xFF).
4. Give CLKI a positive pulse. This loads the address low byte.
