Input: ad7877 - implement specified chip select behavior
According to the AD7877 datasheet:
Each transfer operation is 16-bit. If multiple read/write operations are
to be performed, CS must be taken high after the end of each read/write
operation before another read/write operation can be performed by
taking CS low again.
Make sure CS toggles after each transfer in the message.
