SPECIAL ENVIRONMENT 80960CF-30, -25, -16
271328–45
NOTES:
1. Case 1: DREQ must deassert before DACK deasserts. Applications are Fly-by and some packing and unpacking
modes, in which loads are followed by loads, or stores are followed by stores.
2. Case 2: DREQ must be deasserted by the second clock (rising edge) after DACK is driven high. Applications are non
fly-by transfers and adjacent load-stores or store-loads.
3. DACKx is asserted for the duration of a DMA bus request. The request may consist of multiple bus accesses (defined
by ADS and BLAST. Refer to User’s Manual for ‘‘a(chǎn)ccess’’, ‘‘request’’ definition.

271328–46
NOTE:
EOP has the same AC Timing Requirements as DREQ to prevent unwanted DMA requests.
EOP is NOT edge triggered. EOP must be held for a minimum of 2 clock cycles then EOP must be deasserted
within 15 clock cycles.
