5.3.4.3
Sequential reads are initiated in the same way as a
random read, with the exception that after the
MCP98242 transmits the first data byte, the master
issues an Acknowledge, as opposed to a Stop condi-
tion in a random read. This directs the MCP98242 to
transmit the next sequentially addressed 8-bit word
(Figure

The design will incorporate a low-power Standby mode

termination of any operation and after all internal
functions are complete. This would include any error
conditions occurring, such as improper number of clock
cycles or improper instruction byte as defined
previously.

To provide sequential reads, the MCP98242 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.
