DS83F2
Indicates the start of a digital audio frame in SM3 and SM4, and also the start of a word in
SM1 & SM2.
One of three pins that select the serial mode and function of the multifunction pins.
One of three pins that select the serial mode and function of the multifunction pins.
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).
In serial modes 1 and 2 this pin reflects the value of the DO4 bit in the sub-frame.
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.
In serial mode 4 this pin is the data output for the control port which contains status
information.
In serial modes 1 and 2 this pin reflects the value of the DO3 bit in the sub-frame.
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.
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.
In serial modes 1 and 2 this pin value is reflected in the DI3 bit in the sub-frame.
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.
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.
