Serial Data Interface
(Related Pins) LRCK, BCK, SOUT, SIN, MASL, MLSL
The serial data format is common for both SIN (DA converter
input) and SOUT (AD converter output), consisting of two
channels per sampling serial data represented by 2’s com-
plement. Each channel is divided into 32-bit slots, of which
16 bits are handled as data.
MASL is used to select whether the 16 bits of valid data is
placed in the first or the second half of the 32-bit slots.
Similarly, MLSL is used to select whether the serial data is
arranged at LSB first or MSB first.
