Parallel Port Base Address, Operation Mode and ECP DMA Channel
The Parallel Port Base Address parameter accepts the following values:
• [378h, IRQ 7]
• [3BCh, IRQ 7]
• [278h, IRQ 5]
• [Disabled]
The default setting is [378h, IRQ 7].
The Operation Mode parameter for the parallel port accepts the following:
• [Standard and Bi-directional]
• [Enhanced Parallel Port (EPP)]
• [Extended Capabilities Parallel Port (ECP)]
Enhanced Parallel Port (EPP) provides greater throughput by supporting
faster transfer times and a mechanism that allows the host to address
peripheral device registers directly. Extended Capabilities Port (ECP)
supports a 16-byte FIFO (first in, first out) which can be accessed by host
DMA cycles and PIO cycles.
The default setting is [Standard and Bi-directional].
The ECP DMA Channel parameter lets you set the DMA channel used for
ECP mode. You are required to set a value for this parameter if you select
ECP as your parallel port operation mode. It accepts 1 or 3 as its value.
