CAN interface enable

CONFIG_CAN_ENABLE

  Say Y here to enable one or more CAN cores. The cores has one

  AHB slave interface for accessing the control registers. The CAN core

  is register-compatible with the SAJ1000 core from Philips, with a

  few exceptions. See the GRLIP IP manual for details.

CONFIG_CAN_NUM

  Number of CAN cores. The module allows up to 8 independent

  CAN cores to be implemented.

CAN register address

CONFIG_CANIO

  The control registers of each CAN core occupies 256 bytes, and

  address space needed for the full module is thus 2 Kbyte. The cores

  are mapped in the AHB bus I/O area (0xFFF00000 - 0xFFFFF000).

  This setting defines at which address in the I/O area the registers

  appear (HADDR[19:8]).

CAN interrupt

CONFIG_CANIRQ

  Defines which interrupt number the CAN core will generate.

CAN interrupt

CONFIG_CANSEPIRQ

  Say Y here to assign an individual interrupt to each CAN core,

  starting from the base interrupt number. If set to N, all

  CAN cores will generate the same interrupt.

CAN FT memories

CONFIG_CAN_FT

  If you say Y here, the CAN FIFOs will be implemented using

  SEU protected RAM blocks. Only applicable to the FT version

  of grlib.

CAN Synchronous reset

CONFIG_CAN_SYNCRST

  If you say Y here, the CAN core will be implemented with

  synchronous reset rather than asynchronous. This is needed

  when the target library does not implement registers with

  async reset. Unless you know what you are doing, say N.
