Product data sheet
6.1 Device address
6.2 Control register
Refer to
Following a START condition, the bus master must output the address of the slave it is
accessing. The address of the PCA9532 is shown in
internal pull-up resistors are incorporated on the hardware selectable address pins and
they must be pulled HIGH or LOW.
The last bit of the address byte defines the operation to be performed. When set to logic 1
a read is selected, while a logic 0 selects a write operation.
Following the successful acknowledgement of the slave address, the bus master will send
a byte to the PCA9532, which will be stored in the Control register.
The lowest 4 bits are used as a pointer to determine which register will be accessed.
If the Auto-Increment (AI) flag is set, 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. The contents of these bits will rollover to ‘0000’ after the last
register is accessed.
When Auto-Increment flag is set (AI = 1) and a read sequence is initiated, the sequence
must start by reading a register different from the INPUT0 register
(B3 B2 B1 B0
Only the 4 least significant bits are affected by the AI flag. Unused bits must be
programmed with zeroes.
