XMCK2
O
IC measurement. Low is output normally.
23
TEST
I
Test pin. Normally fixed to Low. Equipped with a pull-down resistor.
24
CLR
I
System clear input. Normally High; cleared when Low. Equipped with a pull-up resistor.

Digital power supply.
26
MS
I
Master/slave mode switching input. Master mode when High; slave mode when Low.
Equipped with a pull-up resistor.
27
LRCK
I/O
Serial I/O sampling frequency clock. Output i master mode (Pin 26 = High); input in slave mode
(Pin 26 = Low). Transfers Channel-1 data when high, and Channel-2 data when Low.
28
BCK
I/O
Serial bit transfer clock (64 f
S
) for serial input data SIN and serial output data SOUT. Output
in master mode (Pin 26 = High); input in slave mode (Pin 26 = Low). Serial input data is re-
trieved at the rising edge; serial output data is transferred at the falling edge.
29
SIN
I
Two channels per sampling serial data input. Data format is represented by 2’s complements,
and consists of 32-bit slots.
30
SOUT
O
Two channels per sampling serial data input. Data format is represented by 2’s complements,
and consists of 32-bit slots.
31

-
Digital GND.
32
MASL
I
Selects whether 16-bit serial data is place din the first 16-bit or the second 16-bit slots of the
serial I/O 32-bit slots. Forward packing when High; rearward packing when Low.
33
MLSL
I
Selects whether 16-bit serial data is input/output at LSB-first or MSB-first. MSB-first when
High; LSB-first when Low.
34
XSL0
I
Crystal selection. Selects the clock frequency to be input from XTLI (Pin 7) using three bits,
XSL 0 to 2.
35
XSL1
I
Crystal selection. Selects the clock frequency to be input from XTLI (Pin 7) using three bits,
XSL 0 to 2.
36
XSL2
I

XSL 0 to 2.
37
DASL0
I
IC measurement. Normally fixed to High.
38
DASL1
I
IC measurement. Normally fixed to Low.
39
WO
I
Synchronization window open input. Window masked when High; window open when Low
(forced synchronization). Equipped with a pull-up resistor.
