NOTES
1
If BR meets the t
and t
setup/hold requirements, it will be recognized in the current processor cycle; otherwise it is recognized in the following cycle. BR requires
a pulse width greater than 10 ns.
2
For 25 MHz only the minimum frequency dependency formula for t
SEC
= (0.25t
CK
– 8.5).
Section 10.2.4, “Bus Request/Grant,” on page 212 of the
ADSP-2100 Family User’s Manual (1st Edition, 1993)
states that “When BR is recognized, the processor
responds immediately by asserting BG during the same cycle.” This is incorrect for the current versions of all ADSP-21xx processors: BG is asserted in the cycle after
BR is recognized. No external synchronization circuit is needed when BR is generated as an asynchronous signal.
