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.
