1
BR
is an asynchronous signal. If
BR
meets the setup/hold requirements, it will be recognized during the current clock cycle; otherwise the signal will be recognized on
the following cycle. Refer to the
ADSP-2100 Family User’s Manual
for
BR
/
BG
cycle relationships.
2
BGH
is asserted when the bus is granted and the processor requires control of the bus to continue.
