An example of a 32-bit write is shown in Table 32. In this ex-
ample, the 32-bit value FFFF DC04h is written to register
address 0Ah. In cycle 1, the high word (FFFFh) is written. In
the first part of cycle 2, the CP3BT10 drives the header, R/
W bit, and register address for a read cycle. In the second
part of cycle 2, the LMX5252 drives the counter value. The

counter value is 0, which indicates one word has been writ-
ten. In cycle 3, the low word (DC04h) is written. In the first
part of cycle 4, the CP3BT10 drives the header, R/W bit,
and register address for a read cycle. In the second part of
cycle 4, the LMX5252 drives the counter value. The counter
value is 1, which indicates two words have been written.
