7.1.2
Internal Agent Transaction for Write Request From Initiator
When each active agent register receives a write request, the internal agent operates with the behavior described
in Table 71. This table assumes that StErPkt at 08h = 0, ErrResp at 08h = 0 and AckPnd at 08h = 0.

Stored in ARF
A successful write to a command agent register returns an acknowledge that depends on Ackpnd at 08h, bit 18.
Table 72 shows the command agent response to a successful write.

ack_pending
The AGENT_STATE register (see Section 7.1.1) is a read-only register. A write request to this register from the
initiator results in an ack_type_error. The error response of the TSB43AA82 depends on the settings of StErPkt and
ErrResp (08h bits 15 and 14). Table 73 shows command agent error responses.
