I have a BF516 based board that must use SPORT1 TX and SPI1 at the same time.
For this I try to use SPORT1 secondary TX data channel only.
Both PRI and SEC TX data channels are configured and feed with data, but only SEC is allowed in PORTH_MUX register and PRI channel pin is used by SPI1.
In this configuration SEC TX pin outputs some strange garbage.
If I enable PRI pin in POTRH_MUX everything works but I cannot use SPI1.
Is this a known hardware limitation and is there any workaround?
