Hardware Mode 2 Description
(DEFAULT Data Flow, Serial Input)
Hardware Mode 2 data flow is shown in Figure 25. Audio data is input via the serial audio input port, and
rate converted. The audio data at the new rate is then output both via the serial audio output port and via
the AES3 transmitter.
The C, U, and V bits in the AES3 output stream may be set in two methods, selected by the CUVEN pin.
When CUVEN is low, mode 2A is selected, where COPY/C, ORIG/U, and EMPH/V pins allow selected
channel status data bits to be set. The COPY and ORIG pins are used to set the pro bit, the copy bit, and
the L bit, as shown in Table 9. In consumer mode, the transmitted category code shall be 0101100b, which
indicates sample rate converter. The transmitted U and V bits are zero.When the CUVEN pin is high, mode
2B is selected, where COPY/C, ORIG/U, and EMPH/V become serial bit inputs for C, U, and V data. This
data is clocked by both edges of OLRCK, and the channel status block start is indicated or determined by
TCBL. Figure 20 shows the timing requirements.
Audio serial port data formats are selected as shown in Tables 6, 7 and 10.
Start-up options are shown in Table 11, and allow choice of the serial audio output port as a master or slave
and whether TCBL is an input or an output. The serial audio input port is always a slave.
