Use
Sends a byte over the HAL’s debug terminal (e.g. serial port). Does nothing if the HAL has been built with debugging disabled.
This is an internal call for OS use only, and its specifications are subject to change without warning. User software requiring the use of low-level debug input/output should prefer to use the function pointers returned by OS_ReadSysInfo 11, as their specification is fixed.
