Figure 19-3. Programming the Flash Waveforms
Note:
1. “XX” is don’t care. The letters refer to the programming description above.
I. Repeat B through H until the entire Flash is programmed or until all data has been
programmed.
J. End Page Programming
1.
1. Set XA1, XA0 to “10”. This enables command loading.
2.
Set DATA to “0000 0000”. This is the command for No Operation.
3.
Give CLKI a positive pulse. This loads the command, and the internal write signals are
reset.
19.6.5
Programming the EEPROM
The EEPROM is organized in pages, see Table 19-9 on page 144. 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 147 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: No action.
K: Repeat 3 through 5 until the entire buffer is filled.
L: Program EEPROM page
1.
Set BS1 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 19-4
for signal waveforms).
