McASPPinDirInputSet() faulty

Martin H.

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

Hi Martin,

To set the Pin direction as Input, the corresponding bit in PDIR (22.4.1.4 Pin Direction Register (PDIR)) must be cleared to '0'.

The API ' McASPPinDirInputSet' is doing just that.

If you need to set the bit to '1' (i,e configure the pin as output) , you will need to use the API 'McASPPinDirOutputSet'.
