15 0 Switching Characteristics
Note 1 ACK is not generated until CS and SWR are low and the NIC has synchronized to the register access In Dual Bus Systems additional cycles will be used
for a local DMA or Remote DMA to complete
Note 2 CS may be asserted before or after SWR If CS is asserted after SWR wackl is referenced from falling edge of CS
