Register Map Summary
The CC has two shadow receive message buffers per channel (four shadow
buffers, in total); these allow reception while the host accesses the receive
message buffers. One additional shadow message buffer is used for internal
operations. Therefore, only 59 buffers out of 64 are available to the user as
message buffers.
