... Control Register. RESET The RESET signals initiate a reset of each modem proces- sor in the ADSP-21mod980N. The RESET signals must be asserted during the power-up sequence to assure proper ini- tialization. RESET during initial power-up must be held long enough to let the internal clocks stabilize. If RESETs are activated any time after power up, the clocks continue to run and do not require stabilization time ...
