1x256-bit data format (BDFS=1, BRLS=1)
This option allows a complete brightness data transfer in a single 256-bit write operation.
The brightness registers BRT01:BRT16 are simultaneously loaded at the falling edge of the
LE signal. Only 65536 steps (16-bit) brightness control is supported by this data format.

1x192-bit data format (BDFS=1, BRLS=0)
The brightness registers BRT01:BRT16 are simultaneously loaded at the end of a single
192-bit single write operation. This option is similar to the 1x256-bit format but optimizes the
serial bus communication when 12 bits only are used for the brightness control.
