8.5.2 sRIO Link Status
The RapidIO “Error Management Extensions Specification” requires specific Configuration Status Registers at desig-
nated addresses. These CSRs are described in section 2 of the identified spec, and should be referenced for more specific
information.
8.5.3 S-Port Link Status
The flags of the “S-Port Link Status”. This flag register is used to identify error that is not covered by the sRIO Error
Management Extensions Specification.
Name: SP_LNK_STAT_FLAG Address: 0x19C04
SP_LNK_STAT_MASK
0x19CC4
This register cannot generate an sRIO packet.

Unused bit
RW Defines whether the sRIO doorbell is an 8 or 16 bit destination ID
RW 0 = Write 8 bits (clear flags only), 1 = Write 32 bits (write new dest IDs)
RW Priority for Doorbell packet

Table 86 S-Port 1 Link Status for Lite Register
Indicates that in response to a previously sent doorbell a “RETRY” indication was received.
8.5.4 Device Configuration Error
These flags are generated whenever a configuration error occurs. When a configuration error occurs the SerB will not
function, however these flags may be masked to create doorbells and interrupts on the ports designated by the masks. All
of these flags are real time (RT) and cannot be cleared except by re-configuring the offending register.
Name: CONFIG_ERR_FLAG
CONFIG_ERR_MASK
Address: 0x19C0C
0x19CCC
If this register generates an sRIO packet, the packet will be a doorbell.
