8 / 12 page  24C32A DS21163B-page 8 Preliminary © 1996 Microchip Technology Inc. 6.3 Contiguous Addressing Across Multiple Devices The device select bits A2, A1, A0 can be used to expand the contiguous address space for up to 256K bits by adding up to eight 24C32A's on the same bus. In this case, software can use A0 of the control byte as address bit A12, A1 as address bit A13, and A2 as address bit A14. 6.4 Sequential Read Sequential reads are initiated in the same way as a ran- dom read except that after the 24C32A transmits the first data byte, the master issues an acknowledge as opposed to the stop condition used in a random read. This acknowledge directs the 24C32A to transmit the next sequentially addressed 8-bit word (Figure 6-3). Following the final byte transmitted to the master, the master will NOT generate an acknowledge but will gen- erate a stop condition. To provide sequential reads the 24C32A contains an internal address pointer which is incremented by one at the completion of each operation. This address pointer allows the entire memory contents to be serially read during one operation. The internal address pointer will automatically roll over from address 0FFF to address 000 if the master acknowledges the byte received from the array address 0FFF.
