7.2 Control register
Following the successful acknowledgement of the slave address, LED All Call address or
LED Sub Call address, the bus master will send a byte to the PCA9624, which will be
stored in the Control register.
The lowest 5 bits are used as a pointer to determine which register will be accessed
(D[4:0]). The highest 3 bits are used as Auto-Increment flag and Auto-Increment options
(AI[2:0]).
When the Auto-Increment flag is set (AI2 = logic 1), the five low order bits of the Control
register are automatically incremented after a read or write. This allows the user to
program the registers sequentially. Four different types of Auto-Increment are possible,
depending on AI1 and AI0 values.
Table 3.
Remark: Other combinations not shown in
reserved and must not be used for proper device operation.
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.

no Auto-Increment
Auto-Increment for all registers. D[4:0] roll over to 00h after the last
register (11h) is accessed.
Auto-Increment for individual brightness registers only. D[4:0] roll over to
02h after the last register (11h) is accessed.
Auto-Increment for global control registers only. D[4:0] roll over to 0Ah’
after the last register (0Bh) is accessed.
Auto-Increment for individual and global control registers only. D[4:0] roll
