SSYNC - Serial Port Sync Signal, PIN 1(L), 39(Q).

Indicates the start of a digital audio frame in SM3 and SM4, and also the start of a word in

SM1 & SM2.

SMODE1 - Serial Mode Select, PIN 29(L), 23(Q).

One of three pins that select the serial mode and function of the multifunction pins.

SMODE2 - Serial Mode Select, PIN 32(L), 26(Q).

One of three pins that select the serial mode and function of the multifunction pins.

SMODE3 - Serial Mode Select, PIN 41(L), 35(Q).

One of three pins that select the serial mode and function of the multifunction pins. This pin

has an internal pull-down making this revision backwards compatible with a previous version

(Revision A or Version3-Version0 bits = 0000).

Multifunction Digital Pins

MF1:DO4 - Parallel Digital Bit Output #4 in SM1/SM2, PIN 40(L), 34(Q).

In serial modes 1 and 2 this pin reflects the value of the DO4 bit in the sub-frame.

MF1:F1 - Format bit 1 in SM3, PIN 40(L), 34(Q).

In serial mode 3 this pin is a format bit and is used as one of three sample frequency select pins

when in master mode, or as one of two bits-per-frame select pins when in slave mode.

MF1:CDOUT - Control Data Output in SM4, PIN 40(L), 34(Q).

In serial mode 4 this pin is the data output for the control port which contains status

information.

MF2:DO3 - Parallel Digital Bit Output #3 in SM1/SM2, PIN 39(L), 33(Q).

In serial modes 1 and 2 this pin reflects the value of the DO3 bit in the sub-frame.

MF2:F2 - Format bit 2 in SM3, PIN 39(L), 33(Q).

In serial mode 3 this pin is a format bit and is used as one of three sample frequency select pins

when in master mode, or as one of two bits-per-frame select pins when in slave mode.

MF2:CDIN - Control Data Input in SM4, PIN 39(L), 33(Q).

In serial mode 4 this pin is the control port data input which contains data such as gain and

attenuation settings as well as input select, mute, and digital output bits.

MF3:DI3 - Parallel Digital Bit Input #3 in SM1/SM2/SM3 (Slave), PIN 35(L), 29(Q).

In serial modes 1 and 2 this pin value is reflected in the DI3 bit in the sub-frame.

MF3:F3 - Format bit 3 in SM3 (Master), PIN 35(L), 29(Q).

In serial mode 3 this pin is a format bit and is used as one of three sample frequency select pins

when in master mode. In slave mode, the pin reverts to being a general purpose input.

MF3:CCLK - Control Data Clock in SM4, PIN 35(L), 29(Q).

In serial mode 4 this pin is the control port serial bit clock which latches data from CDIN on

the falling edge, and outputs data onto CDOUT on the rising edge.
