CHAPTER 18 CAN INTERFACE (RS-CAN LITE)
The number of channels of the CAN module depends the product.
RL78/F13 (LIN incorporated) RL78/F13 (CAN & LIN incorporated) RL78/F14
Channel — 1 1
18.1 Overview
The RL78/F13 and RL78/F14 incorporate one channel of the Controller Area Network (CAN) module conforming to the
ISO11898-1 specifications. Table 18-1 shows the CAN module specifications. Figure 18-1 shows the CAN module block
diagram.
In this chapter, the following variables indicate the number of channels and registers.
• i (i = 0): CAN channel number
• j (j = 0 to 15): CAN receive rule entry register number
(GAFLIDLj, GAFLIDHj, GAFLMLj, GAFLMHj, GAFLPLj, GAFLPHj)
• k (k = 0) : Transmit/receive FIFO buffer number
• m (m = 0, 1): Receive FIFO buffer number
• n (n = 0 to 15): Receive buffer number
• p (p = 0 to 3): Transmit buffer number
• r (r = 0 to 127): CAN RAM test register (RPGACCr) number
