CAN slave and SRAM

[RN]

Hello, 

Thanks for all your wonderful support !

i read the full CAN section in RM of STM32F446RE but could not able to understand how CAN2 differs from CAN1, why CAN2  called as slave ?

its mentioned that , CAN2 cannot access SRAM 

what exactly is the purpose of SRAM?. the RM has no discussion on this 

is it like a shared memory between CAN1 and CAN2 ? 

suppose if i want to receive a CAN message over CAN2, then once it passes acceptance filtering of CAN2 it comes to the FIFO of CAN2 and application reads it . where SRAM comes in to picture ?

Thank you for help.
