Product data sheet
7.2 Control register
Remark: The Software Reset I
as a regular I
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 PCA9625, 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.

Remark: Other combinations not shown in
reserved and must not be used for proper device operation.

Function
no Auto-Increment
Auto-Increment for all registers. D[4:0] roll over to ‘0 0000’ after the last
register (1 1011) is accessed.
Auto-Increment for individual brightness registers only. D[4:0] roll over to
‘0 0010’ after the last register (1 0001) is accessed.
Auto-Increment for global control registers only. D[4:0] roll over to
‘1 0010’ after the last register (1 0011) is accessed.
Auto-Increment for individual and global control registers only. D[4:0] roll
over to ‘0 0010’ after the last register (1 0011) is accessed.
