SPI Interface
SPI Interface
The ADSP-21489 processor has two SPI ports, which can be accessed via
the digital peripheral interface (DPI) pins.
The SPI flash memory, a 16 Mb ST M25P16 device, connects to the SPI
port of the processor and designates:
? DPI pin 5 ( DPI_P5 ) as a chip select
? DPI pin 3 ( DPI_P3 ) as the SPI clock
? DPI pin 1 ( DPI_P1 ) as the master out slave in ( MOSI ) pin
? DPI pin 2 ( DPI_P2 ) as the master in slave out ( MISO ) pin
The same SPI port and DPI pins are connected to the serial flash memory
and audio codec via switch SW3 . See “DPI [1–8] Enable Switch (SW3)” on
page 2-9 . The DPI pins also are available on the expansion interface II.
By default, the EZ-Board boots from the 8-bit flash parallel memory. SPI
flash can be selected as the boot source by setting the boot mode select
switch ( SW4 ) to position 1. See “Boot Mode Select Switch (SW4)” on
page 2-10 .
The audio codec is set up to use DPI pin 4 as the SPI chip select. For more
information, refer to “Audio Interface” on page 1-15 .
Watch Dog Timer Interface
The ADSP-21489 processor includes a 32-bit watch dog timer (WDT)
that can be used to implement a software watch dog function. A software
watch dog can improve system reliability by forcing the processor to a
known state through generation of a system reset if the timer expires
before being reloaded by software. Software initializes the count value of
the timer and then enables the timer.
