Forum Post: McASPPinDirInputSet() faulty

Hello,

the content of the (McASP) PFUNC register is 0 on reset ("22.4.1.3 PFUNC Register").

I would assume that the function

void McASPPinDirInputSet(unsigned int baseAddr, unsigned int pinMask) {   HWREG(baseAddr + MCASP_PDIR) &= ~pinMask;  }

never can set any bit to logic 1,

Or did I miss something?

Regards,
Martin
