Several modes are available when the TLC320AD58C is configured as a slave. Using the Mode0, Mode1,
and Mode2 terminals, the TLC320AD58C can be set to shift out the MSB first or the LSB first [see Figures
2–4(a) and 2–4(b)]. The number of bits shifted out, however, can be controlled by the number of valid SCLK
cycles provided within the left or right channel period. If only enough clocks are provided to shift out 16 data
bits before LRClk changes state, then this is equivalent to a 16-bit mode. Modes 1 and 2 both require 64
SCLK periods per LRClk period.
