Hi,
We are using TMS570LC4357-EP as a SPI master and interfacing it to EEPROM, Serial NOR Flash etc. slave devices.
I was looking into the Technical Reference Manual of TMS570. What I understand from manual is that, TMS570 supports only 2 to 16 BITS per chip-select (§28.2.6.1 Data Formats)
However, our slave device has below requirements (it expects 40 bits per chip select).
I wanted to know if,
- TMS570 supports NUMBER OF WORDS per FRAME (for example, 5 words, each of 16 bits per chip-select)
- TMS570 supports burst operation, where I can read/write large chunk of data from SPI NOR FLASH.
(Note: I read about BURST Transfer in DMA section of MiBSPI(28.3.35 DMA Channel Control Register (DMAxCTRL)) However, I am looking above feature with or without DMA)
Thanks & Regards,
Aravind
