Sequential Read
Sequential reads are initiated in the same way as a
random read except that after the MCP7940N
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
MCP7940N
to
transmit
the
next
sequentially
addressed 8-bit word (Figure 6-6). Following the final
byte transmitted to the master, the master will NOT
generate an Acknowledge but will generate a Stop
condition. To provide sequential reads, the MCP7940N
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 automat-
ically roll over to the start of the Block.
