(14) CAN module last in-pointer register (CnLIPT)
The CnLIPT register indicates the number of the message buffer in which a data frame or a
remote frame was last stored.
Figure 16-37:
CAN Module Last In-Pointer Register (CnLIPT) Format
Remark:
The read value of the CnLIPT register is undefined if a data frame or a remote frame has
never been stored in the message buffer. If the RHPM bit of the CnRGPT register is set to 1
after the CAN module has changed from the initialization mode to an operation mode, there-
fore, the read value of the CnLIPT register is undefined.
