Other Parts Discussed in Thread: TMS320F28335
A question on the TMS320F28335 SPI Status Register's "SPI INT FLAG" bit.
The application note (SPRUEU3A) says that "the SPI hardware sets this bit to indicate that it has completed sending or receiving the last bit and is ready to be serviced".
In my application, when I sent a byte (8bit) data over SPIA port, I saw 8-bit clocks appeared on the SPI bus, but after the completion of the sending, when I read the SPI status register (SPIST), I found that the SPI INT FLAG bit (SPIST.6) was never set to 1, even after a long wait. I wonder why? Did I miss anything in the initializatioin to the SPI port?
