The Channel Provisioning Register is used to provision and unprovision channels, and also to

query the provision status of channels. When a channel is provisioned, chains of packet data for

that channel will be accepted by the TMAC and placed on the channel’s linked list of packets to be

transmitted. When a channel is unprovisioned, chains of packet data for that channel will be

rejected by the TMAC and returned to the TDR Free Queue with the status bits in the queue

element set to indicate the rejection.

Note

This register is not byte addressable. Writing to this register modifies all the bits in the register.

Byte selection using byte enable signals (CBEB[3:0]) are not implemented. However, when all

four byte enables are negated, no access is made to this register.
