RW 0 = Write 8 bits (clear flags only), 1 = Write 32 bits (write new dest IDs)
RW Priority for Doorbell packet
Unused bits
RW Destination ID for sRIO Doorbell
RW Destination ID for sRIO Doorbell, for 16 bit extension
RW S-Port Doorbell Mask
Unused bits
RW Interrupt 0 Mask
RW Interrupt 1 Mask
Table 87 Device Configuration Error Register
Error - This flag indicates that the SerB is programmed to have more memory than is actually attached to
P-Port.
8.5.5 sRIO DMA Status Register
These flags are generated whenever an sRIO error occurs that is not covered by one of the error flags defined in the
sRIO specification. These errors are monitored by the Case Scenarios, so there is one flag register per case scenario.
Name: CS0_DMA_STAT_FLAG Address: 0x19C10
CS0_DMA_STAT_MASK
0x19CD0
If this register generates an sRIO packet, the packet will be a doorbell.
