X24C04
7
Current Address Read
Internally the X24C04 contains an address counter that
maintains the address of the last word accessed,
incremented by one. Therefore, if the last access (either
a read or write) was to address n, the next read operation
would access data from address n + 1. Upon receipt of
the slave address with the R/
W
bit set to one, the
X24C04 issues an acknowledge and transmits the eight
bit word. The read operation is terminated by the master;
by not responding with an acknowledge and by issuing
a stop condition. Refer to Figure 7 for the sequence of
address, acknowledge and data transfer.
Random Read
Random read operations allow the master to access
any memory location in a random manner. Prior to
issuing the slave address with the R/
W
bit set to one,
the master must first perform a “dummy” write opera-
tion. The master issues the start condition, and the
slave address followed by the word address it is to read.
After the word address acknowledge, the master im-
mediately reissues the start condition and the slave
address with the R/
W
bit set to one. This will be followed
by an acknowledge from the X24C04 and then by the
eight bit word. The read operation is terminated by the
master; by not responding with an acknowledge and by
issuing a stop condition. Refer to Figure 8 for the
address, acknowledge and data transfer sequence.
