MSK goes idle again. The MSK idle state can be either high
or low, depending on the MIDL bit.

In Slave mode, the MSK pin is an input for the shift clock
MSK. MDIDO is placed in TRI-STATE mode when MCS is in-

active. Data transfer is enabled when MCS is active.
The slave starts driving MDIDO when MCS is activated. The
most significant bit (lower byte in 8-bit mode or upper byte in
16-bit mode) is output onto the MDIDO pin first. After eight or
sixteen clocks (depending on the selected mode), the data
transfer is completed.
