Description
Serial Audio Bit Clock
The SCLK1/GPIO20, SCLK2/GPIO22 and SCLK3/GPIO35,
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.
Serial Audio Word Clock
The LRCK1/GPIO19, LRCK2/GPIO23 and
LRCK3/GPIO43/AUDIO_CLOCK 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.
LRCK3/GPIO43/AUDIO_CLOCK can be used as the external audio
clock input. If the core clock chosen to be non-audio specific.
Serial Audio Data In
The SDATAI1/GPIO17 and SDATAI3/GPIO8 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. During reset, the pins are
configured as serial data inputs.
Serial Audio Data Out
SDATO1/TOUT0/GPIO18 AND SDATAO2/GPIO34 multiplexed pins can
serve as general purpose I/Os or serial audio outputs. During reset, the
pins are configured as serial data outputs.
Serial audio error flag
The EF/GPIO6 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/GPIO6 is only relevant for serial interface
SDATAI1.
Serial audio CFLG
The CFLG/GPIO5 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/GPIO5 is only relevant for serial interface
SDATAI1.
