Hello I am working on ADSP-21489 EZ-board. I utilize 16-ch PWM for servo ctrl (16pins) , one SPI master working with 4 external slaves (clk, miso,mosi, 4 flags ==>7pins)), another SPIB for load SPI flash (3 pins ) and the UART for GPS com (2 pins). My questions are,
1. Can ADSP-21489 supply with enough pins for above-mentioned periphrals?
Except or 14 pins of DPI, can we multiplex all other signals to external port?
2. The PWM module has four groups of four PWM outputs each, for a total of 16 PWM outputs. Can we config the 16-ch PWM to be independent?
3. Using the EZ board, I practiced to burn my software in SPI flash and run the code without any trouble. I will build my own PCB board and only use the on chip SRAM (5Mb). If I select a 32Mb SPI flash (ROM) with the same brand of that of EZ-board, I would like to know whether I can reuse the loader file.
Thanks in advance
