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.

The LED All Call I²C-bus address allows all the TLC59108Fs in the bus to be programmed at the same time
(ALLCALL bit in register MODE1 must be equal to 1 (power-up default state)). This address is programmable
through the I²C-bus and can be used during either an I²C-bus read or write sequence. The register address can
also be programmed as a Sub Call.
Only the 7 MSBs representing the All Call I²C-bus address are valid. The LSB in ALLCALLADR register is a
read-only bit (0).
If ALLCALL bit = 0 (MODE1 register), the device does not acknowledge the address programmed in register
ALLCALLADR.
