4 0 Device Specifications
Note 1 ADS must be deactivated before state T4 of the external DMA controller cycle
Note 2 During an external DMA cycle WAIT1–2 must be kept inactive unless they are monitored by the DMA Controller An external DMA cycle is similar to a CPU
Note 3 During an external DMA cycle if the ADS signal is pulsed in order to initiate a bus cycle the HOLD signal must remain asserted until state T4 of the DMA
cycle The NS32FX164 generates TSO RD WR ALE and DBE The external DMA controller drives the address data lines HBE ADS and DDIN
