the MOSI pin starting with Bit15, followed by Bit14, Bit13, etc.,
to Bit0. For each fall of the SCLK signal, with CSB held in a
logic low state, a databit is loaded into the shift register per the
databit MOSI state.The shift register is full after sixteen bits of
information have been entered.
MISO Pin
The serial output (MISO) pin is the tri-stateable output
from the shift register. The MISO pin remains in a high
impedance state until the CSB pin goes to a logic low state.
The MISO pin changes state on the rising edge of SCLK and
reads out on the falling edge of SCLK. The MOSI/MISO
shifting of data follows a first-in-first-out protocol with both
input and output words transferring the MSB first.
