(1) R = read, W = write
(2) Default value
Subaddresses are programmable through the I²C Bus. Default power-up values are D2h, D4h, D8h. The
TLC59116-Q1 does not acknowledge these addresses immediately after power-up (the corresponding SUBx bit
in MODE1 register is equal to 0).
Once subaddresses have been programmed to valid values, the SUBx bits (MODE1 register) must be set to 1 to
allows the device to acknowledge these addresses.
Only the 7 MSBs representing the I²C Bus subaddress are valid. The LSB in SUBADRx register is a read-only bit
(0).
When SUBx is set to 1, the corresponding I²C Bus subaddress can be used during either an I²C Bus read or
write sequence.

(1) R = read, W = write
(2) Default value
The LED All Call I²C Bus address allows all the TLC59116-Q1 devices in the bus to be programmed at the same
time (ALLCALL bit in register MODE1 must be equal to 1, which is the 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 seven 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, the device does not acknowledge the address programmed in register ALLCALLADR.
