7.1.4 Software Reset I2C-bus address

The address shown in Figure 4 is used when a reset of the PCA9622 must be performed

by the master. The Software Reset address (SWRST Call) must be used with

R/W = logic 0. If R/W = logic 1, the PCA9622 does not acknowledge the SWRST. See

Section 7.6 “Software reset” for more detail.

Remark: The Software Reset I2C-bus address is a reserved address and cannot be used

as a regular I2C-bus slave address or as an LED All Call or LED Sub Call address.

7.2 Control register

Following the successful acknowledgement of the slave address, LED All Call address or

LED Sub Call address, the bus master sends a byte to the PCA9622, which is stored in

the Control register.

The lowest 5 bits are used as a pointer to determine which register is 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.
