MRBE is the global enable bit for MMRs. On
reset, MRBE is cleared to 0.
0 = MMRs disabled
1 = MMRs enabled
On–Chip Message Buffer RAM (XRAM)
The XA-C3 has a 512–byte on–chip message buffer RAM (XRAM)
which may contain part or all of the CAN/CTL (transmit & receive
objects) message buffers. This block of memory can be accessed
as regular data memory. The logic address of the XRAM is
programmed by software, and must start at a 512–Byte boundary.
The base address of the XRAM is determined by the contents of
Memory Mapped Registers MBXSR and XRAMB as shown in and .
Any address asserted by the XA core (or the DMA) whose fifteen
most significant bits match the concatenation
MBXSR[7:0]XRAMB[7:1] will be automatically routed to the XRAM.
On reset, the XRAM is disabled. Note: The XRAM should not be
confused with the 1K Byte “scratch–pad” DATA RAM which is also
provided on–chip
Since the uppermost 8 bits of all message buffer addresses are
formed by the contents of the MBXSR register, the XRAM and all 32
message buffers must reside in the same 64K byte data memory
segment. Since the XA-C3 only provides address lines A1 – A19 for
accessing External memory, all External memory addresses must
be within the lowest 1M byte of address space. Therefore, if there is
External memory in the system into which anyof the 32 message
buffers will be mapped, then all32 message buffers andthe XRAM
must also be mapped entirely into that same 64K byte segment,
which must be below the 1M byte address limit.
