Baud Rate
UART baud generation divides a peripheral clock according to the MCU's baud-rate generator. Fractional support and register encoding are device-specific.
Identify the block, clock/source dependencies, data path and interfaces.
Follow the target reference manual and change only documented fields.
Define the expected register state, timing or signal before running the test.
Inspect software state and measure hardware behavior rather than guessing.
From manual to measurement
- Read the architecture/reference-manual section.
- Identify clocks, pins, memory, interrupts and dependencies.
- Calculate required timing or configuration values.
- Implement the smallest working configuration.
- Build with warnings enabled and flash the target.
- Inspect registers and measure the external behavior.
- Document failures, assumptions and the final fix.
