CAN 1 to 3 interrupt enable registers (C1IE to C3IE)
The CxIE registers enable the transmit, receive and error interrupts of the corresponding CAN mod-
ule x (x = 1 to 3).
These registers can be read in 8-bit and 16-bit units. It can be written in 16-bit units only. For setting
and clearing certain bits a special set/clear method applies (refer to chapter 13.3.1).
