CPU/DMA Block Transfer
The SCC provides a Block Transfer mode to accommodate CPU block transfer functions
and DMA controllers. The Block Transfer mode uses the WAIT/REOUEST output in con-
junction with the Wait/Request bits in WR1. The WAIT/REOUEST output can be
defined under software control as a WAIT line in the CPU Block Transfer mode or as a
REQUEST line in the DMA Block Transfer mode.
To a DMA controller, the SCC REQUEST output indicates that the SCC is ready to trans-
fer data to or from memory To the CPU, the WAIT line indicates that the ESCC is not
ready to transfer data, thereby requesting that the CPU extend the I/O cycle. The DTR/
REQUEST line allows full-duplex operation under DMA control.
SCC Data Communications Capabilities
The SCC provides two independent full-duplex programmable channels for use in any
common asynchronous or synchronous data communication protocols (see
page 19). Each data communication channel has identical feature and capabilities.
