CODE EXAMPLE 4-9
shows the Ethernet output message.
4.7.9.4 Parallel Port
The parallel port diagnostic performs the
dma_read
. This enables the enhanced
capability port (ECP) mode configuration, ECP DMA configuration, and FIFO test
mode. It transfers 16 bytes of data from the memory to the parallel-port device, then
verifies that the data is in FIFO test.
CODE EXAMPLE 4-10
shows the parallel-port
output message.
