Hello,
I try to config the McBSPB Pins as a SPI Master. I used the example from the ControlSUITE.
Now my question: There are 6 Pins for the McBSP_B (MDXB, MDRB, MCLKXB, MFSXB, MCLKRB, MFSRB).
For the SPI Master I only need 4 Pins (MDXB=MOSI, MDRB=MISO, MCLKXB=CLK, MFSXB=CS).
Is it possible to use the Pins MCLKRB and MFSRB for other functions e.g. for PWM or do I
also have to mux them as McBSP Pins although I do not need them in a SPI Master wiring?
In the datasheet I found following:
"The receive clock signal (MCLKR) and receive frame-synchronization signal (FSR) are not used in the
clock stop mode because these signals are internally connected to their transmit counterparts, CLKX and
FSX."
Although it says that I do not have to wire the pins, it does not say that I can use it otherwise.
I am looking forward to your answer.
Best regards,
Werner
