1.
Applies after the power-up sequence is complete. At power up, the Internal Phase Locked Loop requires no more than 1000 CLKIN cycles
while RESET is low, assuming stable VDD and CLKIN (not including clock oscillator start-up time).
2.
Specification only applies in cases where multiple TSC21020F processors are required to execute in program counter lock-step (all
processors start execution at location 8 in the same cycle). See the Hardware Configuration chapter of the ADSP-21020 User’s Manual from
Analog Devices for reset sequence information.

Meeting setup and hold guarantees interrupts will be latched in that cycle. Meeting the pulse width is not necessary if the setup and hold is met.
Likewise, meeting the setup and hold is not necessary if the pulse width is met. See the Hardware Configuration chapter of the ADSP-21020
User’s Manual from Analog Devices for interrupt servicing information.
