Figure 98. Programming the Flash Waveforms
Note:
“XX” is don’t care. The letters refer to the programming description above.
Programming the
EEPROM
The EEPROM is organized in pages, see Table 106 on page 236. When programming the
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 “Programming the Flash” on page 237 for details on Command, Address and
Data loading):
1.
A: Load Command “0001 0001”.
2.
G: Load Address High Byte (0x00 - 0xFF).
3.
B: Load Address Low Byte (0x00 - 0xFF).
4.
C: Load Data (0x00 - 0xFF).
5.
E: Latch data (give PAGEL a positive pulse).
K: Repeat 3 through 5 until the entire buffer is filled.
L: Program EEPROM page
1.
Set BS to “0”.
2.
Give WR a negative pulse. This starts programming of the EEPROM page. RDY/BSY
goes low.
3.
Wait until to RDY/BSY goes high before programming the next page
(See Figure 99 for signal waveforms).
