Recommended Port Setting Value for CAN, MFS, and Communication Features in Traveo S6J3XXX MCUs – KBA218100

Version: *A

Translation - Japanese: Traveo S6J3XXX MCUのCAN, MFSおよび通信機能の推奨ポート設定値 - KBA218100 - Community Translated (JA)

Question:

What are the recommended values for the following registers in the Traveo™ S6J3110/3120 series MCUs: PPC_PCFGR:NFE and EICxx_NFER:NFEx?

Answer:

Port setting for CAN, multi-function serial (MFS), and communication features of the input should be as follows:

PPC_PCFGR:NFE=0, EICxx_NFER:NFEx=[0 or 1]

When you use both CAN and external interrupts, use the following setting:

PPC_PCFGR:NFE=0, EICxx_NFER:NFEx=1

In the case of the “PPC_PCFGR:NFE=1” setting, both CAN/MFS and external interrupt of the input ports have a noise filter; for the “EICxx_NFER:NFEx=1” setting, only the external interrupt of inputs have a noise filter.

You can set the CAN/MFS of the input ports such that they have no noise filter and only the external input ports have a noise filter in the “PPC_PCFGR:NFE=0, EICxx_NFER:NFEx=1” setting.

Note: This KBA applies to the following series of Traveo MCUs:

  • S6J3110
  • S6J3120
