MCP3550/1/3
If 24 bits of data are required from this conversion, they
must be accessed during this communication. You can
terminate data transition by bringing CS high, but the
remaining data will be lost and the converter will go into
Shutdown mode. Once the data has been transmitted
by the converter, the SDO/RDY pin will remain in the
LSB state until the 25th falling edge of SCK. At this
point, SDO/RDY is released from the Data Acquisition
mode and changed to the RDY state.

It is possible to use only two wires to communicate with
the MCP3550/1/3 devices. In this state, the device is
always in Continuous Conversion mode, with internal
conversions continuously occurring. This mode can be
entered by having CS low during power-up or changing
it to a low position after power-up. If CS is low at power-
up, the first conversion of the converter is initiated
approximately 300 µs after the power supply has
stabilized.

Note:
The RDY state is not latched to CS in this
mode; the RDY flag dynamically updates
on the SDO/RDY pin and remains in this
state until data is clocked out using the
SCK pin.
