8-bit Fm+ I 2 C-bus 100 mA 40 V LED driver
AI[2:0] = 110 is used when the LED drivers must be globally programmed with different
settings during the same I 2 C-bus communication, for example, global brightness or
blinking change.
AI[2:0] = 111 is used when individual and global changes must be performed during the
same I 2 C-bus communication, for example, changing a color and global brightness at the
same time.
Only the 5 least significant bits D[4:0] are affected by the AI[2:0] bits.
When the Control register is written, the register entry point determined by D[4:0] is the
first register that will be addressed (read or write operation), and can be anywhere
between 0 0000 and 1 0001 (as defined in Table 4 ). When AI[2] = 1, the Auto-Increment
flag is set and the rollover value at which the register increment stops and goes to the next
one is determined by AI[2:0]. See Table 3 for rollover values. For example, if the Control
register = 1110 0100 (E4h), then the register addressing sequence will be (in
hexadecimal):
04 ? … ? 0B ? 02 ? … ? 0B ? 02 ? … ? 0B ? 02 ? … ? 0B ? 02 ? … as long
as the master keeps sending or reading data.

Only D[4:0] = 0 0000 to 1 0001 are allowed and will be acknowledged. D[4:0] = 1 0010 to 1 1111 are reserved and will not be
acknowledged.
When writing to the Control register, bit 4 must be programmed with logic 0 for proper device operation.
