Operation Theory

53

The operations sequence of digital output in burst handshaking
mode are listed:

1. Define the input configuration to be 32-bit, 16-bit or 8-bit

data width.

2. Enable or disable the active terminators.

3. Define the output clock as burst handshaking mode and

decide the timer pacer rate to be 20Mhz, 10Mhz, or the
output of 82C54 timer 1.

4. Connect the handshaking signals of the external device

to output pin DO-REQ and input pin DO-ACK.

5. Define the starting mode to be NoWait, TrigWait, Wait-

FIFO, or WaitBoth

6. Digital output data is moved from PC’s system memory

to output FIFO by using bus mastering DMA.

7. After output data is ready. DO-REQ signals are gener-

ated and sent the output data to the external device
when the DO-ACK is asserted.
