General Description
1.4.17 CAN Receive Pin (CANRx)/BDLC Receive Pin (BDRxD)
If the part is configured as MC68HC08AZ32 emulator protocol, this pin is the digital input to the CAN
module (CANRx). Otherwise, if the part is configured as MC68HC08AS20 emulator protocol, this pin is
the serial digital input to the BDLC module (BDRxD). See Chapter 23 MSCAN Controller or Chapter 28
Byte Data Link Controller-Digital (BDLC-D).
