3FF7 : PORT_C[15..8] DATA REGISTER. READ AND WRITE.

3FF8: PORT_C[7..0] DIRECTION REGISTER. WRITE ONLY.

AN ‘1’ IN THIS REGISTER WILL SET THE CORRESPONDING PIN OF PORT_C TO BE OUTPUT.

THE DEFAULT VALUE FOR EACH BIT IS ZERO.

3FF9: PORT_C[15..8] DIRECTION REGISTER. WRITE ONLY.

AN ‘1’ IN THIS REGISTER WILL SET THE CORRESPONDING PIN OF PORT_C TO BE OUTPUT.

THE DEFAULT VALUE FOR EACH BIT IS ZERO.

3FFA :ADC REGISTER. READ ONLY.

WHEN THE TIMER B NMI OCCURS, THE A/D CONVERSION PROCESS STARTS AND THE S/H

CIRCUIT STOP SAMPLING AND BEGIN HOLDING IT UNTIL THE

ADC PROCESS IS FINISHED.

THE ADC INT WILL GENERATE WHEN ADC PROCESS IS FINISHED.
