AIF + AI[1:0] = 101b is used when the 16 LED drivers must be individually programmed
with different values during the same I
setting to another color setting.
AIF + AI[1:0] = 110b is used when the LED drivers must be globally programmed with
different settings during the same I
or blinking change.
AIF + AI[1:0] = 111b is used when the 16 LED drivers must be individually programmed
with different values in addition to global programming.
Only the 6 least significant bits D[5:0] are affected by the AIF, AI1 and AI0 bits.
When the Control register is written, the register entry point determined by D[5:0] is the
first register that will be addressed (read or write operation), and can be anywhere
between 0h and 26h (as defined in
and the rollover value at which the register increment stops and goes to the next one is
determined by AIF, AI1 and AI2. See
register bit AI1 = 0 and AI0 = 1 and if the Control register = 1001 0010, then the register
addressing sequence will be (in hex):
20
as the master keeps sending or reading data.
