Table 7.
Legend: * default value.
Subaddresses are programmable through the I
E4h, E8h, and the device(s) will not acknowledge these addresses right after power-up
(the corresponding bits [3:1] in MODE register is equal to 0).
Once subaddresses have been programmed to their right values, bits [3:1] (MODE
register) must be set to logic 1 in order to have the device acknowledging these
addresses. Only the seven MSBs representing the I
LSB in SUBADRx register is a read-only bit (0). When subaddress control bits [3:1] in
MODE register is set to logic 1, the corresponding I

same time (bit 0 in register MODE must be equal to 1 (power-up default state)). This
address is programmable through the I
read or write sequence. Only the seven MSBs representing the All Call I
are valid. The LSB in ALLCALLADR register is a read-only bit (0). If bit 0 in MODE
register = 0, the device does not acknowledge the address programmed in register
ALLCALLADR.
