Chapter 10 Freescale’s Scalable Controller Area Network (S12MSCANV2)
10.3.3
The following section details the organization of the receive and transmit message buffers and the
associated control registers.
To simplify the programmer interface, the receive and transmit message buffers have the same outline.
Each message buffer allocates 16 bytes in the memory map containing a 13 byte data structure.
An additional transmit buffer priority register (TBPR) is defined for the transmit buffers. Within the last
two bytes of this memory map, the MSCAN stores a special 16-bit time stamp, which is sampled from an
internal timer after successful transmission or reception of a message. This feature is only available for
transmit and receiver buffers, if the TIME bit is set (see
(CANCTL0)”).
The time stamp register is written by the MSCAN. The CPU can only read these registers.

identifiers. The mapping of standard identifiers into the IDR registers is shown in
All bits of the receive and transmit buffers are ‘x’ out of reset because of RAM-based implementation
All reserved or unused bits of the receive and transmit buffers always read ‘x’.
1. Exception: The transmit priority registers are 0 out of reset.
