The slave address which ISP1123 uses to access the EEPROM is 1010000B. Page
mode addressing is not supported, so pins A0, A1 and A2 of the EEPROM must be
connected to GND (logic 0).
11.3 Data transfer
When the ISP1123 is reset, the I
2
C-bus interface tries to read 6 bytes of configuration
data from an external EEPROM. If no response is detected, the levels on inputs SDA
and SCL are interpreted as INDV and OPTION to select the operating mode (see
Table 4
).
The data in the EEPROM memory are organized as shown in
Table 22
.
