Other Parts Discussed in Thread: CONTROLSUITE
According to the datasheet, TMX320F28377D PTP package has the GPIO99 port.
Does it exist?
Isn't there a mistake in the datasheet?
Thanks,
I use TI's basic example. (See attatched source file and capture image)
GPIO27 is work well(pin's logic state changed). But, GPIO99 is not work.
