Table 13.
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 SUBx bit in MODE1 register is equal to 0).
Once subaddresses have been programmed to their right values, SUBx bits need to be
set to logic 1 in order to have the device acknowledging these addresses (MODE1
register).
Only the 7 MSBs representing the I
register is a read-only bit (0).
When SUBx is set to logic 1, the corresponding I

as a Sub Call.
Only the 7 MSBs representing the All Call I
ALLCALLADR register is a read-only bit (0).
If ALLCALL bit = 0, the device does not acknowledge the address programmed in register
ALLCALLADR.
