No function assigned. Fix to "0."

EIM

0: Mask (disable) interrupt request

CAN bus error interrupt request mask bit

1: Enable interrupt request

PIM

Error passive interrupt request mask bit

OIM

Bus off interrupt request mask bit

(1) EIM (CAN Bus Error Interrupt Request Mask) bit (Bit 13)

The EIM bit enables or disables the interrupt requests to be generated when CAN bus errors occurred. CAN

bus error interrupt requests are enabled by setting this bit to "1."

(2) PIM (Error Passive Interrupt Request Mask) bit (Bit 14)

The PIM bit enables or disables the interrupt requests to be generated when the CAN module entered an

error passive state. Error passive interrupt requests are enabled by setting this bit to "1."

(3) OIM (Bus Off Interrupt Request Mask) bit (Bit 15)

The OIM bit enables or disables the interrupt requests to be generated when the CAN module entered a bus

off state. Bus off interrupt requests are enabled by setting this bit to "1."
