... This pin can be connected to either V floating. An internal pull-down resistor on this pin will keep the device in the unprotected state if left floating. If tied left floating, normal memory operation SS is enabled (read/write the entire memory 0000-3FFF). If tied WRITE operations are inhibited. Read CC operations are not affected. 3.0 ...

DEVICE ADDRESSING A control byte is the first byte received following the start condition from the master device (Figure 5-1). The control byte consists of a 4-bit control code; for the 24xx128 this is set as 1010 binary ...

... But instead of generating a stop condi- tion, the master transmits additional bytes, which are temporarily stored in the on-chip page buffer and will be written into memory after the master has transmitted a stop condition. After receipt of each word, the six lower address pointer bits are internally incremented by one ...

ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (This feature can be used to maximize bus throughput.) Once the stop condition for a ...

... Random Read Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, first the word address must be set. This is done by sending the word address to the 24xx128 as part of a write operation (R/W bit set to 0). ...
