* For PSWP A
0 is at normal CMOS levels and for RSWP, A0 is at VHV which must be held high beyond the end
of the STOP condition (approximately 1
s of “overlap” is sufficient).
address counter can be ‘initialized’ by performing a
‘dummy’ WRITE operation (Fig. 12). The START
condition is followed by the Slave address (with the R/
W
bit set to ‘0’) and the desired byte address. Instead of
following up with data, the Master then issues a 2nd
START, followed by the ‘Immediate Address Read’
sequence, as described earlier.

Sequential Read
If the Master acknowledges the 1st data byte transmitted
by the CAT34RC02, then the device will continue
transmitting as long as each data byte is acknowledged
by the Master (Fig. 13). If the end of memory is reached
during sequential READ, the address counter will ‘wrap-
around’ to the beginning of memory, etc. Sequential
READ works with either ‘Immediate Address Read’ or
‘Selective Read’, the only difference being the starting
byte address.
