Cannot find details on configuring TJA1443 transceiver

[RChatterjee]

I was going over the code for https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K344-FlexCAN-Ip-TX-RX-EnhanceRXFIFO-test... by @PetrS , recommended in this post: https://community.nxp.com/t5/S32K/FlexCAN-driver-on-S32K3X4EVB-T172-EVB-can-t-access-via-PCAN/td-p/1... . I want to understand where the configuration information is present (TJA1153_START_ID, TJA1153_CONFIG_ID ) , i.e. if I had to do it from scratch, where would I find this config id in the datasheet. I am having trouble locating it.

Hi,

do you use TJA1443 or TJA1153, in fact?
TJA1443 does not require any special initialization, it has 2 control pins, EN and STB_N, which are used to switch between device modes.
TJA1153 is secure CAN transceiver and if not previously configured or is in default Vanilla state, it requires configuration over CAN either from host or remotely. All needed info about that process can be found on device web page under Documentation section. Most of documents or driver is given as Secure Files, so you need to have registered and NDA signed to access files; https://www.nxp.com/support/support/secure-access-rights:SEC-ACCESS

Oh, ok. The answer in the referred post indicated otherwise.
