4-bit Fm+ I 2 C-bus low power LED driver
7.1.4 Software reset I 2 C-bus address
The address shown in Figure 7 is used when a reset of the PCA9632 needs to be
performed by the master. The Software Reset address (SWRST Call) must be used with
R/W = 0. If R/W = 1, the PCA9632 does not acknowledge the SWRST. See Section 7.5
“ Software       reset   ” for more detail.

Software reset address
Remark: The Software Reset I 2 C-bus address is a reserved address and cannot be used
as a regular I 2 C-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 will send a byte to the PCA9632, which will be
stored in the Control register.
The lowest 4 bits are used as a pointer to determine which register will be accessed
(D[3:0]). The highest 3 bits are used as Auto-Increment flag and Auto-Increment options
(AI[2:0]). Bit 4 is unused and must be programmed with zero (0) for proper device
operation.

Remark: The Control register does not apply to the Software Reset I 2 C-bus address.

Control register
When the Auto-Increment flag is set (AI2 = 1), the four 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.
