NOTES:
1) THE MOUSE CHECKS THE DATA LINE. IF THE LINE IS LOW, THE SYSTEM HAS DATA TO TRANSMIT.
THE DATA LINE IS SET INACTIVE WHEN THE START BIT (ALWAYS 0) IS PLACED ON THE DATA LINE.
2) THE MOUSE SAMPLES THE DATA LINE FOR EACH BIT WHILE THE CLK LINE IS HIGH.
DATA MUST BE STABLE WITHIN 1 MICROSECOND AFTER THE RISING EDGE OF THE CLK LINE.
3) THE MOUSE CHECKS FOR A HIGH STOP BIT AFTER THE 10TH CLK. IF THE DATA LINE IS LOW,
THE MOUSE CONTINUES TO CLOCK UNTIL THE DATA LINE BECOMES HIGH, THEN CLOCKS THE
LINE-CONTROL BIT, AND AT THE NEXT OPPORTUNITY SENDS A RESEND COMMAND TO THE SYSTEM.
4) THE MOUSE PULLS THE DATA LINE LOW, PRODUCING THE LINE-CONTROL BIT.
5) THE HOST CAN PULL THE CLK LINE LOW, INHIBITING THE MOUSE.

NOTES:
1) THE HOST CAN HOLD THE CLOCK SIGNAL LOW TO INHIBIT THE NEXT TRANSMISSION.
2) THE HOST RAISES THE CLOCK LINE TO ALLOW THE NEXT TRANSMISSION.
3) ALL TIMES GIVEN BELOW ASSUME AN 18.432 MHz RESONATOR AND ARE DEPENDENT UPON ITS ACCURACY.
