When the CnLIPT register is read, the contents of the element indexed by the last
0.....31 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.
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.
