7.1.4 Software reset I
7.2 Control register
The address shown in
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
“Software reset”
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 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.
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.
