TJA1102 Reset

Hello NXP,

I am integrating TJA1102 with SJA1105 switch and MC S32K344.

Is it mandatory to issue a software reset (Bit 15) in the Basic Control Register (Register 0) after initializing the transceiver?

My initialization sequence is:

1- Set Bit 2 (CONFIG_EN) Register 17

2- Set Bit 0 (PHY_EN) Register 28

3- Set whether PHY acting as Master/Slave (Bit 15) Register 18

4- Clear AUTO_OP (Bit 15) in Register 28.

Do I need to apply Software reset (Bit 15 in Reg 0) after issuing the above initialization sequence? Also, do you recommend for any missing initializing step?

Thanks
