Detailed Description

Structure for MCAN Message RAM Configuration Parameters.

Message RAM can contain following sections:

Standard ID filters,
Extended ID filters,
Rx FIFO0,
Rx FIFO1,
Rx Buffers,
Tx Event FIFO,
Tx Buffers,
Tx FIFO (or Tx Queue)

Note: If any section in the message RAM is not used then its size should be initialized to '0'. (Number of buffers in case of Tx/Rx buffer).
