we have designed custom boards for the ADSP-21573 in two versions:
- one booting DSP in SPI master mode from flash
- one booting DSP in SPI slave mode from another processor
(1.) Is 10k the recommended value for the pull up resistor for PC00 / nSPI2_RDY (as seen in the HWR p.45-29) ?
(2.) How is the pin PC00 involved in booting in SPI master mode from flash ?
We experience the need to pull it up to VCC to make the DSP start reading from flash after Reset / Power Up.
Thanks in advance,
