TLRDRD—CSR Read Data Return Data Register
Address BSB + 0800
Access W
The TLRDRD register is used by I/O nodes to return data read
from a remote CSR window space read command and complete the
remote CSR read command. The CPU virtual ID is asserted on the
TLSB_BANK_NUM<3:0> signals when this command is issued. The
CPU virtual ID came from the CPU during the CSR window space
read command.
