PCA9633
4-bit Fm+ I 2 C-bus LED driver
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 PCA9633, 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 ?ag 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.
Fig 10. Control register
When the Auto-Increment ?ag 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.

Auto-Increment for individual and global control registers only. D3, D2,
D1, D0 roll over to ‘0010’ after the last register (0111) is accessed.
Remark: Other combinations not shown in Table 6 (AI[2:0] = 001, 010, and 011) are
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 2 C-bus communication, for example, changes the brightness of a single LED. Data
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 four LED drivers must be individually programmed with
different values during the same I 2 C-bus communication, for example, changing color
setting to another color setting.
