DOUT
DOUT provides the 14 data bits only (and S1, S0).
The 14 d ata b i ts ( and S 1, S 0) ar e cl ocked out M S B fi r st at D O U T, on the l ast
16 cl ock ed g es of the cur r ent r ead com m and w or d . S ee Fi g ur es 8, 9, and 10.
For write commands, DOUT follows DIN after 32 clocks. The entire 32-bit
write command word (both command word and data) is clocked out MSB
first at DOUT. For read commands, the 14 data bits (and S1, S0) of the
selected register are valid at DOUT starting with the first clock falling edge
after the falling edge of CS (see Fi g ur es 6 and 7) .
DOUT provides the 14 data bits (and S1, S0) of the selected register from
the current read command word. The 14 data bits (and S1, S0) are clocked
out MSB first at DOUT on the last 16 clock edges of the current read
command word (see Figures 8, 9 and 10).
