SCIBRR = 0xC9), the wrong break duration occur-
rence is around 1%.
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:
262/265
- Disable interrupts
- Reset and Set TE (IDLE request)
- Set and Reset SBK (Break Request)
- Re-enable interrupts
LIN mode
If the LINE bit in the SCICR3 is set and the M bit in
the SCICR1 register is reset, the LINSCI is in LIN
master mode. A single break character is sent by
setting and resetting the SBK bit in the SCICR2
register. In some cases, the break character may
have a longer duration than expected:
- 24 bits instead of 13 bits
