https://community.nxp.com/t5/Other-NXP-Products/SJA1105-without-Host-Processor/m-p/1828584#M21638 <P>Hello,<BR />If I understand the datasheet correctly, the&nbsp;<SPAN>SJA1105 Ethernet Switch <EM>requires&nbsp;</EM>a host processor to load the configuration. This means that I cannot operate the device in a default mode without a processor connected to the SPI port. Did I understand that correctly?&nbsp;<BR /><BR />Thanks in advance.</SPAN></P> Thu, 14 Mar 2024 15:03:23 GMT ttel 2024-03-14T15:03:23Z https://community.nxp.com/t5/Other-NXP-Products/SJA1105-without-Host-Processor/m-p/1828584#M21638 <P>Hello,<BR />If I understand the datasheet correctly, the&nbsp;<SPAN>SJA1105 Ethernet Switch <EM>requires&nbsp;</EM>a host processor to load the configuration.
