15 0 Switching Characteristics
Note 1 The first port request is issued in response to the remote write command It is subsequently issued on T1 clock cycles following completion of remote DMA
cycles
Note 2 The start of the remote DMA write following WACK is dependent on where WACK is issued relative to BSCK and whether a local DMA is pending
