NOTES
1If BR meets the t
BS and tBH 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.
Section 10.2.4, “Bus Request/Grant,” 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.
