SCI Parity  GT16A

Enabling parity on this beast requires that the SCI be placed into 9-bit mode, parity enabled, parity type selected. Fine.

I imagine that on receive the SCI shifts in the proper parity value into SCIxC3 bit R8.

However a full chip simulation run shows that bit T8 is not automatically computed/set on a transmit, simply by loading SCIxD. I don't know if I should trust the simulator. But if true that means that my code will have to compute the parity bit, set T8, then load SCIxD.

Is this a true picture? Alas I'm away from the hardware today and can't run any experiments.

Al, a no-parity guy by inclination. But one must deal with marketing...
