TODO
  • Fix Standby mode wakeup.

    Make list of shared interrupt pins with most amount of MCUs. -SubTODO- use unused interrupt as to make integration easier.

    Find & test alternative can transceivers. Have plenty of TJAs & 82c. Awaiting arrival of TJR1443, which are probably perfection, with dedicated wkup/error pin. -SubTODO- Implement TJR properly, to allow error reading.

    Implement external wakeup as well.

SD Card in AWAKE & STOP eats 7-8mA more.
