SERIAL COMMUNICATIONS
Communication with the device is done using a
standard SPI-compatible serial interface. Initiating
communication with the MCP3201 device begins with
the CS going low. If the device was powered up with the
CS pin low, it must be brought high and back low to
initiate communication. The device will begin to sample
the analog input on the first rising edge after CS goes
low. The sample period will end in the falling edge of the
second clock, at which time the device will output a low
null bit. The next 12 clocks will output the result of the
conversion with MSB first, as shown in Figure 5-1. Data
is always output from the device on the falling edge of
the clock. If all 12 data bits have been transmitted and
the device continues to receive clocks while the CS is
held low, the device will output the conversion result
LSB first, as shown in Figure 5-2. If more clocks are
provided to the device while CS is still low (after the
LSB first data has been transmitted), the device will
clock out zeros indefinitely.

* After completing the data transfer, if further clocks are applied with CS low, the A/D Converter will output LSB first data, followed
by zeros indefinitely. See Figure 5-2 below.
** tDATA: during this time, the bias current and the comparator power-down and the reference input becomes a high-impedance
node, leaving the CLK running to clock out the LSB-first data or zeros.
