STV2050A - MASTER I²C BUS INTERFACE
– STX[0] =´EEPROM PROBLEM´
6.6 DATA TRANSFER BETWEEN RAM AND EEPROM
Data is transfered using the following I²C BUS sequence after a bit in the E9 register has been
read or written: S DW SA D0 D1 D2 P
Where:
– SA = E9: Selection of the E9 register, EEPROMadd[2:0] is the hardware EEPROM address
– RWM[2:0] selects the Read or Write mode as previously described,
– HAM[2:0]: Hamming code used to protect the D0[7:0] and D1[7:4] data bits. Refer to
The total transfer lasts approximately 200 ms if the I²C master clock is operating at 70 kHz.
30/83
ADD 7
If A Read or Write sequence has been terminated with an access error, the STX[0] bit is set
to low. It is set back to high when the master starts the next R/W sequence.
