Table 9. Serial Audio Interface Signals
The SCLK1, SCLK2/GPIO48 and SCLK3/GPIO49, and
SCLK4/GPIO50 multiplexed pins can serve as general purpose I/Os or
serial audio bit clocks. As bit clocks, these bidirectional pins can be
programmed as outputs to drive their associated serial audio (IIS) bit
clocks. Alternately, these pins can be programmed as inputs when the
serial audio bit clocks are driven internally. The functionality is
programmed within the Audio module. During reset, these pins are
configured as input serial audio bit clocks.
The LRCK1, LRCK2/GPIO44, LRCK3/GPIO45, and LRCK/GPIO46
multiplexed pins can serve as general purpose I/Os or serial audio
word clocks. As word clocks, the bidirectional pins can be programmed
as inputs to drive their associated serial audio word clock. Alternately,
these pins can be programmed as outputs when the serial audio word
clocks are derived internally. The functionality is programmed within
the Audio module. During reset, these pins are configured as input
serial audio word clocks.
The SDATAI1, SDATAI3/GPIO41, and SDATAI4/GPI42 multiplexed pins
can serve as general purpose I/Os or serial audio inputs. As serial
audio inputs the data is sent to interfaces 1and 3 respectively. The
functionality of these pins is programmed with the GPIO-FUNCTION
and GPIO1-FUNCTION registers. During reset, the pins are configured
as serial data inputs.
The SDATAO1/GPIO25 AND SDATAO2/GPI41 multiplexed pins can
serve as general purpose I/Os or serial audio outputs. The functionality
of these pins is programmed with registers GPIO-FUNCTION and
GPIO1-FUNCTION. During reset, the pins are configured as serial
data outputs..
The EF/GPIO19 multiplexed pin can serve as general purpose I/Os or
error flag input. As error flag input, this pin will input the error flag
delivered by the CD-DSP. EF/GPIO19 is only relevant for serial
interface interface 1.
The CFLG/GPIO18 multiplexed pin can serve as general purpose I/O
or CFLG input. As CFLG input, the pin will input the CFLG flag
delivered by the CD-DSP. CFLG/GPIO18 is only relevant for serial
interface 1.
