Workaround
If this wrong duration is not compliant with the
communication protocol in the application, soft-
ware can request that an Idle line be generated
before the break character. In this case, the break
duration is always correct assuming the applica-
tion is not doing anything between the idle and the
break. This can be ensured by temporarily disa-
bling interrupts.
The exact sequence is:
- Disable interrupts
- Reset and Set TE (IDLE request)
160/163
1
- Set and Reset SBK (Break Request)
- Re-enable interrupts
15.2 FLASH DEVICES ONLY
15.2.1 Internal RC Operation
In ST72F324J and ST72F324K devices, the inter-
nal RC oscillator is not supported if the LVD is dis-
abled.
