Is there any additional feature supported in CANFD on SC598 compared to SC594 ?

  • Yes, CANFD in SC598 supports pretended networking in STOP mode as well as DOSE modes where as in SC594 pretended networking was not possible in STOP mode. IN SC598 there are additional bits MISCREG_CAN_SYSCTL_CAN0_IPG_STOP_CLK_EXT and MISCREG_CAN_SYSCTL_CAN1_IPG_STOP_CLK_EXT in MISCREG_CAN_SYSCTL register which control the clock to CANFD MMR registers during STOP mode. These are used to ensure that the clock to CANFD registers is on while rest of the CANFD module clock is gated. This allows software to read CANFD register to complete the sequence for pretended networking in STOP mode.
