PARAMETER MEASUREMENT INFORMATION
All timing parameters are referenced to VIH and VIL. Bit 1 = MSB (most significant bit) and is clocked in first on DIN
or clocked out first on DOUT. Bit n = LSB (least significant bit) and is clocked in last on DIN or is clocked out last on
DOUT. N = 8 for the companded mode, and N = 16 for the linear mode.
