#130216 - Can't single step on UART Responding to: ???'s previous message |
I'm using the Keil Evaluation IDE and when I step through my program I can't see when an interrupt trips Return to your original question, On SiLabs C8051 family, UART doesn't work properly while single step is done on the debugger (SiLabs IDE or Keil uVision). The baudrate generator clock which drives the UART is also "single-stepped". The UART TX/RX timing is collapsed. From SiLabs MCU Knowledge base 7491: "Code Profiling Techniques" http://portal.knowledgebase.net/article.a...491&p=4120 Note that other communication peripherals, UART, SPI, External Memory Interface, Timers, etc., are held in lock-step with code execution.
