PCA9634
8-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 PCA9634, 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 ?ag and Auto-Increment options
(AI[2:0]).

Remark: The Control register does not apply to the Software Reset I 2 C-bus address.
Fig 7.
Control register
When the Auto-Increment ?ag is set (AI2 = 1), the ?ve 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.

register (1 0001) is accessed.

Auto-Increment for individual brightness registers only. D[4:0] roll over to

Auto-Increment for global control registers only. D[4:0] roll over to

Auto-Increment for individual and global control registers only. D[4:0] roll
over to ‘0 0010’ after the last register (0 1011) is accessed.
Remark: Other combinations not shown in Table 3 (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.
