PCA9530
2-bit I 2 C-bus LED dimmer
The last bit of the address byte de?nes the operation to be performed. When set to logic 1
a read is selected, while a logic 0 selects a write operation.
6.2 Control register
Following the successful acknowledgement of the slave address, the bus master will send
a byte to the PCA9530, which will be stored in the Control register.

Control register
The lowest 3 bits are used as a pointer to determine which register will be accessed.
If the Auto-Increment ?ag is set, the three low order bits of the Control register are
automatically incremented after a read or write. This allows the user to program the
registers sequentially. The contents of these bits will rollover to ‘000’ after the last register
is accessed.
When Auto-Increment ?ag is set (AI = 1) and a read sequence is initiated, the sequence
must start by reading a register different from the Input register (B2 B1 B0 ≠ 0 0 0).
Only the 3 least signi?cant bits are affected by the AI ?ag. Unused bits must be
programmed with zeroes.
