MCP41XXX/42XXX
5.8
It is possible to operate the devices in SPI modes 0,0
and 1,1. The only difference between these two modes
is that, when using mode 1,1, the clock idles in the high
state, while in mode 0,0, the clock idles in the low state.
In both modes, data is clocked into the devices on the
rising edge of SCK and data is clocked out the SO pin
once the falling edge of SCK. Operations using mode
0,0 are shown in Figure 5-1. The example in
Figure 5-5 shows mode 1,1.

There must always be multiples of 16 clocks while CS is low or commands will abort.
The serial data out pin (SO) is only available on the MCP42XXX device.

loaded on rising
edge of CS. Shift
register is loaded
with zeros at this time.
SO pin will always
drive low when CS
goes high.
