4. ata Sheet 2 4 Rev 2 1 2013 02 26 TLE983x BD Infineon First recommendation ensure an input signal rise time of lt 15us If this is not possible 3 cases need to be distinguished In case only rising edges are evaluated no workaround is required In case only falling edges are evaluated the errata described above occurs No workaround is available for this case In case both edges are used for interrupt generation but depending on the edge different actions should be taken e g in CCU6 following workaround can be used Table 1 rising edge signalled falling edge signalled action no no no action no yes handle as falling yes no handle as rising yes yes handle as rising 4 Application hints 4 1 LIN overcurrent shutdown In the design step BD the automatic LIN overcurrent shutdown has been removed The LIN transceiver is not disabled automatically any more the protection is ensured by the overcurrent limitation feature The overcurrent events is signalled in LIN OC_STS and needs to be handled by software interrupt or polling in case it appears in the specified LIN operational range 4 2 LIN Transceiver enabling with slow ramping With the default setting of register PCU_CTRL_STS 2 the LIN Transceiver is disabled whenever VS under voltage condition is met VS lt 5 5V It has to be ensured by software sequence that only after leaving the VS under voltage condition VS gt 5 5V which can
