Figure 21-3. Programming the Flash Waveforms
Note:
The EEPROM is organized in pages, see
EEPROM, the program data is latched into a page buffer. This allows one page of data to be
programmed simultaneously. The programming algorithm for the EEPROM data memory is as
follows (refer to
Data loading):
A: Load Command “0001 0001
G: Load Address High Byte (0x00 - 0xFF).
B: Load Address Low Byte (0x00 - 0xFF).
C: Load Data (0x00 - 0xFF).
E: Latch data (give PAGEL a positive pulse).
K: Repeat A through E until the entire buffer is filled.
L: Program EEPROM page

RDY/BSY
1. Set BS1 to “0”.
2. Give WR a negative pulse. This starts programming of the EEPROM page. RDY/BSY
3. Wait until to RDY/BSY goes high before programming the next page (See
