SPI Flash
The ADSP-BF706 processor has three SPI interfaces: SPI0, SPI1, and
SPI2. SPI2 is connected to a Winbond W25Q32BC 32 Mb serial flash
memory with dual and quad SPI support. This flash is used for booting
and scratchpad space. The boot mode of the ADSP-BF706 EZ-KIT Mini
is SPI master, which is set by resistors on the board.
For more information, refer to the SPI flash example in the POST, which
is included in the ADSP-BF706 EZ-KIT Mini Board Support Package.
Audio Codec
The ADAU1761 (
U2
) is a SigmaDSP® low power, stereo audio codec
(24 bits) connected to the ADSP-BF706 EZ-KIT Mini through TWI and
SPORT0 interfaces. Line-in is provided through a 3.5 mm audio jack (
J1
)
and headphone connected to a 3.5 mm jack (
J2
). When cables are
inserted, the loopback from
J2
to
J1
is disconnected.
C
onnector
P7
allows connection to the unused microphone and line-out
functionality of the audio codec.
