■ CAN CONTROLLER
The MB90440G series contains three generic CAN controllers (CAN0, CAN1, CAN2) .
The CAN controller has the following features :
Conforms to CAN Specification Version 2.0 Part A and B
- Supports transmission/reception in standard frame and extended frame formats
Supports transmission of data frames by receiving remote frames
16 transmission/reception message buffers
- 29-bit ID and 8-byte data
- Multi-level message buffer configuration
Provides full-bit comparison, full-bit mask, acceptance register 0/acceptance register 1 for each message
buffer as ID acceptance mask
- Two acceptance mask registers in either standard frame format or extended frame formats
Bit rate programmable from 10 Kbps to 1 Mbps (when input clock is at 16 MHz)
