• TCCA: An eight-bit time clock/counter A. In MOUSE mode, it will load X -axis data into TCCA, it is
• TCCB: An eight-bit time clock/counter B. In MOUSE mode, it will load Y-axis data into TCCB, it is
• TCCC: An eight-bit time clock/counter C. In MOUSE mode, it will load Z-axis data into TCCC, it is
• Bit 7~Bit 3 Not used, read as ‘0’.
• Bit 2(TCCAIE) TCCAIF interrupt enable bit.
• Bit 1(TCCATS) TCCA signal source
• Bit 0(TCCATE) TCCA signal edge
