1 IE Interrupt Enable
This bit globally enables and disables interrupts (error, status-change, and
message object transmit and receive interrupts).
0 = disable interrupts
1 = enable interrupts
When the IE bit is set, an interrupt is generated only if the corresponding
interrupt source’s enable bit (EIE or SIE in CAN_CON; TXIE or RXIE in
CAN_MSG
x
_CON0) is also set. If the IE bit is clear, an interrupt request
updates the CAN interrupt pending register, but does not generate an
interrupt.
