In MCAN mode, the static TR consists of the following information:
Param | PSIL Addr | Field | Description |
---|---|---|---|
Burst | 0x400 | 31 | Not used |
Acc32 | 0x400 | 30 | When set, enables 32-bit access mode. On a 32-bit PDMA, all accesses will have XCNT=4 to support legacy IP that is not fully VBUSP compliant. This bit is ignored if the PDMA VBUSP port is not 32 bits wide. |
X | 0x400 | 26:24 | Not used |
Y | 0x400 | 11:0 | Buffer Size. This field specifies how many bytes should be written to an MCAN TX buffer. This field includes the 8 byte MCAN header on the initial packet fragment. The PDMA will break up the source packet into fragments of this buffer size, copying the 8 byte MCAN header for the initial fragment, and then skipping it for each additional fragment and thus reusing the header from the first fragment. A buffer size less than 16 is treated as 16, and a buffer size greater than 72 is treated as 72. |
Z | 0x401 | 23:0 | Not used |
