This register defines the FIFO valid byte count register and PCI bus request control for Channel
X
in the
SiI
3114.
The register bits are defined below.
The FIFO Write Request Control and FIFO Read Request Control fields in these registers provide threshold
settings for establishing when PCI requests are made to the Arbiter. The Arbiter arbitrates among the four
requests using fixed priority with masking. The fixed priority is, from highest to lowest: channel 0; channel 1;
channel 2; and channel 3. If multiple requests are present, the arbiter grants PCI bus access to the highest
priority channel that is not masked. That channel’s request is then masked as long as any unmasked requests are
present.
Bit [31:25]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [24:16]
: FIFO Valid Byte Count (R). This bit field provides the valid byte count for the data FIFO for
Channel
X
. A value of 000
H
indicates empty, while a value of 100
H
indicates a full FIFO with 256 bytes.
Bit [15:11]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [10:08]
: FIFO Wr Req Ctrl (R/W) – FIFO Write Request Control. This bit field defines the FIFO
threshold to assign priority when requesting a PCI bus write operation. A value of 00
H
indicates that write
request priority is set whenever the FIFO contains greater than 32 bytes, while a value of 07
H
indicates that
write request priority is set whenever the FIFO contains greater than 7x32 bytes (=224 bytes). This bit field
is useful when multiple DMA channels are competing for the PCI bus.
Bit [07:03]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [02:00]
: FIFO Rd Req Ctrl (R/W) – FIFO Read Request Control. This bit field defines the FIFO
threshold to assign priority when requesting a PCI bus read operation. A value of 00
H
indicates that read
request priority is set whenever the FIFO has greater than 32 bytes available space, while a value of 07
H
indicates that read request priority is set whenever the FIFO has greater than 7x32 bytes (=224 bytes)
available space. This bit field is useful when multiple DMA channels are competing for accessing the PCI
bus.

: Chnl3 Int Block (R/W) – Channel3 Interrupt Block. This bit is set to block interrupts from Channel
3.
