Currently we are using TJA1145A ASIC.

If we move to TJA1445A ASIC, Is it possible to use same driver software or there is a changes in registers address?

Hi,

there is updated SPI protocol and optimized register map in TJA1445 so existing SW have to be modified.
There is migration guide available within TJA1445 webpage under Secure File section, so you can refer to it.
