REC
Receive error count value

During an error active/error passive state, a receive error count value is stored in this register.
The count is decremented when frames are received normally or incremented when an error occurred. If the
CAN module finished receiving normally when REC
≥
128 (error passive), REC is set to 127. During a bus off
state, an undefined value is stored in this register. The count is reset to H’00 upon returning to an error active
state.

During an error active/error passive state, a transmit error count value is stored in this register.
The count is decremented when frames are transmitted normally or incremented when an error occurred. Dur-
ing a bus off state, an undefined value is stored in this register. The count is reset to H’00 upon returning to an
error active state.
