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.
