Hi,

It is necessary to perform read-back functions in register configuration? Why?

ie:

mcasp1Regs->PFUNC = 0x0;

while(mcasp1Regs->PFUNC != 0x0);

Regards,

Well, it might not be strictly necessary, but it is prudent.

It can take several cycles for the value of the register to take effect, so I would not recommend proceeding without checking.

And is it not necessary for KICK and PINMUX registers?
