Function
Error Code Capture: when the CAN controller detects
a bus error, the location of the error within the frame is
captured in this field. The value reflects an internal
state variable, and as a result is not very linear:
Start of Frame
ID28 ... ID21
ID20 ... ID18
SRTR Bit
IDE bit
ID17 ... 13
ID12 ... ID5
ID4 ... ID0
RTR Bit
Reserved Bit 1
Reserved Bit 0

When the CAN controller detects a bus error, the
direction of the current bit is captured in this bit.
Error occurred during transmitting.
Error occurred during receiving.
When the CAN controller detects a bus error, the type
of error is captured in this field:
