Timing Requirements:
tBH
BR Hold after CLKOUT High1
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.
