Table 457. Used ID-Look-up Table sections
Explicit standard frame format identifier section (11-bit CAN ID):
The start address of the Explicit Standard Frame Format section is defined in the SFF_sa
register with the value of 0x00. The end of this section is defined in the SFF_GRP_sa
register. In the Explicit Standard Frame Format section of the ID Look-up Table two CAN
Identifiers with their Source CAN Channels (SCC) share one 32-bit word. Not used or
disabled CAN Identifiers can be marked by setting the message disable bit.
Group of standard frame format identifier section (11-bit CAN ID):
The start address of the Group of Standard Frame Format section is defined with the
SFF_GRP_sa register with the value of 0x10. The end of this section is defined with the
EFF_sa register. In the Group of Standard Frame Format section two CAN Identifiers with
the same Source CAN Channel (SCC) share one 32-bit word and represent a range of
CAN Identifiers to be accepted. Bit 31 down to 16 represents the lower boundary and bit
15 down to 0 represents the upper boundary of the range of CAN Identifiers. All Identifiers
within this range (including the boundary identifiers) will be accepted. A whole group can
be disabled and not used by the acceptance filter by setting the message disable bit in the
upper and lower boundary identifier. To provide memory space for four Groups of
Standard Frame Format identifiers, the EFF_sa register value is set to 0x20. The identifier
group with the Index 9 of this section is not used and therefore disabled.
Explicit extended frame format identifier section (29-bit CAN ID,
The start address of the Explicit Extended Frame Format section is defined with the
EFF_sa register with the value of 0x20. The end of this section is defined with the
EFF_GRP_sa register. In the explicit Extended Frame Format section only one CAN
Identifier with its Source CAN Channel (SCC) is programmed per address line. To provide
memory space for four Explicit Extended Frame Format identifiers, the EFF_GRP_sa
register value is set to 0x30.
Group of extended frame format identifier section (29-bit CAN ID,
The start address of the Group of Extended Frame Format is defined with the
EFF_GRP_sa register with the value of 0x30. The end of this section is defined with the
End of Table address register (ENDofTable). In the Group of Extended Frame Format
section the boundaries are programmed with a pair of address lines; the first is the lower
boundary, the second the upper boundary. To provide memory space for two Groups of
Extended Frame Format Identifiers, the ENDofTable register value is set to 0x40.
