The Demo Board of PT7A6525 in DMA Mode

Brief

This Demo Board shows a simplified application of PT7A6525 (or PT7A6526) in DMA transfer mode. It

demonstrates a typical circuit design of the interface between PT7A6525 and system bus, CPU, DMA control-

ler, system memory etc. in DMA transmission mode. This board adopts a short loop in transferring rate 4.096M

bps between TxD and RxD of Channel B of PT7A6525. This communication works as a point-point connection.

Because PT7A6526 has a same channel as Channel B of PT7A6525, it can work in this demo board normally,

too.

The demo board uses MC68HC000 as CPU, and 8237 as DMA controller. PT7A4402 provides clock signals to

the transmitter and receiver of PT7A6525. An EPLD is used to generate control bus signals.

This application note introduces the principle of this DMA tranfer application and the operation of the demo

program on PC. This program can be used to read or write the register contents of PT7A6525, and transfer or

read the data in system memory.
