Description

31-30

SP_MODE

SRIO Port IP Mode of operation.

00

1x/4x LP-Serial RapidIO Specification

01

4 ports (1x mode each)

10

Reserved

29

IDLE_ERR_DIS

IDLE Error checking disable.

0

Error checking enabled (default), only |K|, |A| and |R| characters are available. If input receives any
other characters in idle sequence, it should enter the Input-Error-stopped state.

1

Error checking disabled, all not idle or invalid characters during idle sequence are ignored

28

TX_FIFO_BYPAS

Transmit FIFO

S

0

The TX_FIFO is operational (Default)

1

The TX_FIFO is bypassed. The txbclk and the sys_clk must be locked during operation, but the
phase variation up to 1 clock cycle is allowable. The 4 deep FIFO is used to accommodate the
phase difference.

27

PW_DIS

Port-Write Disable.

0

Enable Port-Write Error reporting (default)

1

Disable Port-Write Error reporting

26

TGT_ID_DIS

Destination ID Decode Disable- Definition of packet acceptance by the physical layer.

0

Packet accepted if DestID = Base ID. When DestID is not equal to Base ID, the packet is ignored;
i.e., it is accepted by RapidIO port but is not forwarded to logical layer.

1

Packet accepted with any DestID and forwarded to the logical layer.

25

SELF_RST

Self reset enable, when 4 Link-Request Reset Control Symbols are accepted.

0

Self reset interrupt disabled (default), interrupt signal is asserted

1

Self reset interrupt enabled, the reset signal is asserted by the SRIO_TE reset controller. The
SRIO_TE configuration registers are set to the default value after reset and loose a boot
initialization values.

5

MLTC_EN

Multicast-Event Interrupt Enable. If enabled, the interrupt signal is High when the Multicast-Event
control symbol is received by any port.

0b

Multicast interrupt disable

1b

Multicast interrupt enable

4

MLTC_IRQ

Multicast-Event Interrupt Status bit. It is High when the Multicast-Event control symbol is received
by any port. Once set, it remains set until written with logic 1 to clear. The mltc_irq output signal is
driven by this bit.
