<strong>RL78</strong>/<strong>D1A</strong> CHAPTER 14 CAN CONTROLLER<br />

(15) CAN module last in-pointer register (C0LIPT, C1LIPT)<br />

The C0LIPT, C1LIPT register indicates the number of the message buffer in which a data frame or a remote<br />

frame was last stored.<br />

LIPT7-LIPT0 Last In-Pointer Register (C0LIPT, C1LIPT)<br />

0 to 15 When the C0LIPT, C1LIPT register is read, the contents of the element indexed by the<br />

last in-pointer (LIPT) of the receive history list are read. These contents indicate the<br />

number of the message buffer in which a data frame or a remote frame was last stored.<br />

Remark The read value of the C0LIPT, C1LIPT register is undefined if a data frame or a remote<br />

frame has never been stored in the message buffer. If the RHPM bit of the C0RGPT,<br />

C1RGPT register is set to 1 after the CAN module has changed from the initialization<br />

mode to an operation mode, therefore, the read value of the C0LIPT, C1LIPT register<br />

is undefined.<br />
