MC68360 Autobaud Operation Application Note
Technical guidance for implementing autobaud operation on the NXP MC68360, including SCC to BRG mapping and interrupt initialization sequences.
Overview
This application note describes the requirements and initialization procedures for successful autobaud operation on the MC68360 processor. It specifies that Serial Communications Controllers (SCC) must be mapped to their corresponding Baud Rate Generators (BRG) for autobaud to function. The document provides a detailed sequence for configuring the BRGCx register and SCC receiver to ensure the SCC is properly clocked before enabling the autobaud (AB) bit, which is necessary to trigger the ATB lock interrupt.
Use Cases
- Implementing automatic baud rate detection in serial communications
- Configuring NXP MC68360 SCC and BRG modules
- Troubleshooting autobaud interrupt failures in QUICC processors
