2.3.3 Update Main Memory (SLE 4432 and SLE 4442)
The command programs the addressed EEPROM byte with the data byte transmitted. Depending
on the old and new data, one of the following sequences will take place during the processing mode:
– erase and write
– write without erase
– erase without write
(5 ms)
(2.5 ms) corresponding to m = 124 clock pulses
(2.5 ms) corresponding to m = 124 clock pulses
corresponding to m = 255 clock pulses
(All values at 50 kHz clock rate.)
