Register summary
7.3 Register definitions
AI[2:0] = 000 is used when the same register must be accessed several times during a
single I
is overwritten each time the register is accessed during a write operation.
AI[2:0] = 100 is used when all the registers must be sequentially accessed, for example,
power-up programming.
AI[2:0] = 101 is used when the 16 LED drivers must be individually programmed with
different values during the same I
setting to another color setting.
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 1011 (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 = 1111 0100 (F4h), then the register addressing sequence will be (in hex):
14
as the master keeps sending or reading data.
