4.5.2.4.1. Port-Write Transmission
- DESTINATION_ID
- priority
- wrsize
The other fields of the MAINTENANCE port-write packet are assigned as follows. The ftype is assigned a value of 4'b1000 and the ttype field is assigned a value of 4'b0100. The wdptr and wrsize fields of the transmitted packet are calculated from the size of the payload to be sent as defined by the size field of the Tx Port Write Control register. The source_tid and config_offset are reserved and set to zero.
The payload is written to a Tx Port Write Buffer starting at address 0x10210. This buffer can store a maximum of 64 bytes. The port-write processor starts the packet composition and transmission process after the PACKET_READY bit in the Tx Port Write Control register is set. The composed Maintenance port-write packet is sent to the Transport layer for transmission.
