Name
Read/write value indicating selected interrupt level.
Bits3-0 select the interrupt level used for interrupt 0. A value of 1 selects IRQL 1, a value
of 15 selects IRQL 15. IRQL 0 is not a valid interrupt selection and (represents no
interrupt selection.
Read/write value that indicates the type and level of the interrupt request level selected in
the previous register.
If a card supports only one type of interrupt, this register may be read-only.
Bit 0 - Type of the interrupt request selected in the previous register.
Bit1 - Level of the interrupt request selected in the previous register. (See also Section
13.1 on page 231).
Read/write value indicating selected DMA channel for DMA 0.
Bits 2-0 select the DMA channel for DMA 0. A value of 0 selects DMA channel 0; a
value of 7 selects DMA channel 7.
Selecting DMA channel 4, the cascade channel, indicates that no DMA channel is
active.
Read/write value indicating selected DMA channel for DMA 1
Bits 2-0 select the DMA channel for DMA 1. A value of 0 selects DMA channel 0; a
value of 7 selects DMA channel 7.
Selecting DMA channel 4, the cascade channel, indicates that no DMA channel is
active.
