LDRx = 00 : LED driver x is off (default power-up state).
LDRx = 01 : LED driver x is fully on (individual brightness and group dimming/blinking not controlled).
LDRx = 10 : LED driver x is individual brightness can be controlled through its PWMx register.
LDRx = 11 : LED driver x is individual brightness and group dimming/blinking can be controlled through its PWMx
register and the GRPPWM registers.

(1) R = read, W = write
(2) Default value
Sub-addresses are programmable through the I²C bus. Default power-up values are 92h, 94h, 98h 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 sub-addresses 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 I²C bus sub-address are valid. The LSB in SUBADRx register is a read-only
bit (0).
When SUBx is set to 1, the corresponding I²C bus sub-address can be used during either an I²C bus read or
write sequence.
