NOTE:
1. A
0L — A14L ≠ A0R — A14R
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
maximum rating conditions for extended periods may affect reliability.
2. V
TERM must not exceed Vcc + 0.3V.
3. Ambient Temperature Under Bias. No AC Conditions. Chip Deselected.
NOTES:
1. This is the parameter T
A. This is the "instant on" case temperature.
NOTES:
1. V
IL > -1.5V for pulse width less than 10ns.
2. V
TERM must not exceed Vcc + 0.3V.
NOTES:
1. This parameter is determined by device characterization but is not production
tested.
2. C
OUT also references CI/O.
NOTE:
1. There are eight semaphore flags written to via I/O
0 and read from all I/O's (I/O0-I/O7). These eight semaphores are addressed by A0-A2
