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.
Register summary
7.3 Register definitions
AI[2:0] = 110 is used when the LED drivers must be globally programmed with different
settings during the same I
blinking change.
AI[2:0] = 111 is used when individual and global changes must be performed during the
same I
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
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
register = 1110 0100 (E4h), then the register addressing sequence will be (in hex):
