15.10.12 CAN Interrupt Clear Register (CICLR)
The CICLR register bits individually clear CAN interrupt
pending flags caused by the message buffers and from the
Error Management Logic. Do not modify this register with in-
structions that access the register as a read-modify-write
operand, such as the bit manipulation instructions.

ICLR
15.10.13 CAN Interrupt Code Enable Register (CICEN)
The CICEN register controls whether the interrupt pending
flag in the CIPND register is translated into the Interrupt
Code field of the CSTPND register. All interrupt requests,
CAN error, and message buffer interrupts can be enabled/
disabled separately for the interrupt code indication field.

The Error Interrupt Clear bit is used to clear
the EIPND bit.
0 – The EIPND bit is unaffected by writing 0.

15.10.14 CAN Status Pending Register (CSTPND)
The CSTPND register holds the status of the CAN Node
and the Interrupt Code.
NS
IRQ/IST
15
Reserved
The CAN Node Status field indicates the sta-
tus of the CAN node as shown in Table 48.
The IRQ bit and IST field indicate the interrupt
source of the highest priority interrupt current-
ly pending and enabled in the CICEN register.
Table 49 shows the several interrupt codes
when the encoding for all interrupt sources is
enabled (CICEN = FFFFh).
