Figure 881. Slave Node — One Tx Filter Configuration - STMicroelectronics SPC572L series Reference Manual

LINFlexD
50.5.2.5 At least one TX filter, BF is reset, ID matches filter
This configuration can be used in case slave never receives data, for example, sensor.
50.5.2.6 At least one RX filter, BF reset, ID matches filter
50.5.2.7 RX only, TX only, RX & TX filters, ID not matching filter, BF reset
50.5.2.8 TX filter, BF is set
This configuration is used when:
•
All TX IDs are handled by filters.
•
There are not enough other filters to handle all reception IDs.
