This bit is cleared when LERR bit in LINSIR is cleared.
This bit is cleared when LERR bit in LINSIR is cleared.
This bit is cleared when LERR bit in LINSIR is cleared.
Gives the number of samples of a bit.
sample-time = (1 /
Default value: LBT[6:0]=32 — Min. value: LBT[6:0]=8 — Max. value: LBT[6:0]=63
These bits are reserved for future use. For compatibility with future devices, they must be
written to zero when LINBRR is written.
The LDIV value is used to scale the entering clk
UART baud rate.
