5.3.4
Read operations are initiated in the same way as write
operations, with the exception that the R/W bit of the
slave address is set to ‘1’. There are three basic types
of read operations: current address read, random read,
and sequential read.
TABLE 5-5:
5.3.4.1
The MCP98242 contains an address counter that
maintains the address of the last word accessed,
internally incremented by ‘1’. Therefore, if the previous
access (either a read or write operation) was to
address
would access data from address
the slave address with R/W bit set to ‘1’, the MCP98242
issues an acknowledge and transmits the 8-bit data
