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.

Here's an accounting of where the power is going on Proteus with the STM32 in standby mode.

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