Interrupt Number

and Wake-Up on

IRQ Enable

Indicates selected interrupt number.

Bits 7-5: Reserved.

Bit 4: Enables wake-up on the IRQ of the logical device. When enabled, IRQ as-

sertion triggers a wake-up event.

Disabled (default)

Enabled

Bits 3-0: select the interrupt number. A value of 1 selects IRQ1, a value of 2 selects

IRQ2, etc. (up to IRQ15). A value of 0 disables this interrupt.

7116

Interrupt Request

Type Select

Indicates the type and level of the interrupt request number selected in the previous

Bits 7-2: Reserved.

Bit 1: Polarity of interrupt request selected in previous register

0: Low polarity

1: High polarity

Bit 0: Type of interrupt request selected in previous register

DMA Channel

Select 0

Indicates selected DMA channel for DMA 0 of the logical device (0: The ﬁrst DMA

channel if more than one DMA channel is used).

Bits 7-3: Reserved.

Bits 2-0: Select the DMA channel for DMA 0. The valid choices are 0-3, where:

●

A value of 0 selects DMA channel 0, 1 selects channel 1, etc.

●

A value of 4 indicates that no DMA channel is active.

●

The values 5-7 are reserved.

7516

DMA Channel

Select 1

Indicates selected DMA channel for DMA 1 of the logical device (1: The second

DMA channel if more than one DMA channel is used).

Bits 7-3: Reserved.

Bits 2-0: Select the DMA channel for DMA 1. The valid choices are 0-3, where:

●

A value of 0 selects DMA channel 0, 1 selects channel 1, etc.

●

A value of 4 indicates that no DMA channel is active.

●

The values 5-7 are reserved.
