Absolute Maximum Ratings(1)
Capacitance(1) (TA = +25°C, f = 1.0MHz)
Truth Table II: Semaphore Read/Write Control(1)
NOTE:
1. There are eight semaphore flags written to via I/O0 and read from I/O0 - I/O7. These eight semaphores are addressed by A0 - A2.
NOTES:
1. This is the parameter TA. This is the "instant on" case temperature.
2
Industrial temperature: for specific speeds, packages and powers contact
your sales office.
NOTE:
1. A0L – A12L is not equal to A0R – A12R
