NOTE:
1. There are eight semaphore flags written to via I/O

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Exposure
to absolute maximumrating conditions for extended periods may affect
reliability.

must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum and is limted to < 20mA for the period of V

> Vcc + 10%.
NOTES:
1. This is the parameter T

. There is the "instant on" case temperature.
NOTES:
1. V
