Last in-pointer register (CnLIPT)
When the CnLIPT register is read, the contents of the element indexed by the last in-pointer
(LIPT) of the receive history list are read. These contents indicate the number of the
message buffer in which a data frame or a remote frame was last stored.

CnLIPT - CANn module last in-pointer register
The CnLIPT register indicates the number of the message buffer in which a
data frame or a remote frame was last stored.
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 CnRGPT.RHPM bit
is set to 1 after the CAN module has changed from the initialization mode to an
operation mode, therefore, the read value of the CnLIPT register is undefined.
