7.3.8 LED All Call I
7.4 Power-on reset
7.5 Software reset
Once subaddresses have been programmed to their right values, SUBx bits need to be
set to 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 1, the corresponding I
