A control byte is the first byte received following the.

Start condition from the master device Figure The control byte consists of a four-bit control code. The next three bits datashheet the control byte.

The Chip Select bits in the control byte must.

The last bit of the control byte defines the operation to. The upper address bits are transferred. Following the Start condition, the 24XX32A monitors.

In this case, software can use A0 of the con. A2 as address bit A It is not possible to sequentially.

The Chip Select bits allow the use of up to eight 24XX32A devices on the same bus and are used to select which device is accessed. The Chip Select bits in the control byte must correspond to the logic levels on the corresponding A2, A1 and A0 pins for the device to respond.

These bits are in effect the three Most Significant bits of the word address. For the SOT and chip scale packages, the address pins are not available. The last bit of the control byte defines the operation to be performed.

When set to a zero, a write operation is selected. The next two bytes received define the address of the first data byte Figure The upper address bits are transferred first, followed by the Less Significant bits.

In this case, software can use A0 of the con- trol byte as address bit A12; A1 as address bit A13; and A2 as address bit A It is not possible to sequentially read across device boundaries. The Ratasheet and chip scale packages do not support multiple device addressing on the same bus.
