Section 20 Controller Area Network (RCAN-TL1)
20.8 Setting I/O Ports for RCAN-TL1
The I/O ports for the RCAN-TL1 must be specified before or during the configuration mode. For
details on the settings of I/O ports, see section 27, Pin Function Controller (PFC). Two methods
are available using two channels of the RCAN-TL1 in this LSI.
• Using RCAN-TL1 as a 2-channel module (channels 0 and 1)
Each channel has 32 Mailboxes.
• Using RCAN-TL1 as a 1-channel module (channels 0 and 1 functioning as a single channel)
When the second method is used, see section 20.9.1, Notes on Port Setting for Multiple Channels
Used as Single Channel.
Figures 20.28 and 20.29 show connection examples for individual port settings.
