Hi GrWa_2302706,
The hardware supports only up to 16 mail boxes. But you can use the acceptance filters to receive a range of message IDs in a single mailbox. Please refer to the CAN troubleshooting guide for information on how to set AMR and ACR registers to achieve this.For more information, see section 16.5.2 Acceptance Filter PSoC 4100S and PSoC 4100S Plus: PSoC 4 Architecture TRM, Document No. 002-10621 Rev. *I

Just clarify my question. Is there way to receive specific ID data from CAN host ? As the problem happens when there are several nodes in CAN system while no problem when only one node (CY8C4147).

Hi GrWa_2302706,
In the CAN configurator, you can make use of Full Receive mailbox to receive only messages with a specific ID. For example,
The mailbox one is configured as Full will receive only message with ID 0x01.
Hope this helps!
