Product data sheet
6.1 Device address
6.2 Control register
Table 3.
Refer to
Following a START condition, the bus master must output the address of the slave it is
accessing. The address of the PCA9533/01 is shown in
PCA9533/02 is shown in
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 PCA9533, which will be stored in the Control register.
The lowest 3 bits are used as a pointer to determine which register will be accessed.
If the Auto-Increment (AI) flag 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 flag 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
Only the 3 least significant bits are affected by the AI flag. Unused bits must be
programmed with zeroes.
