IMPORTANT NOTES (Cont’d)
Impact on application
Software may execute the interrupt routine twice
after header reception.
Moreover, in reception mode, as the receiver is no
longer in mute mode, an interrupt will be generat-
ed on each data byte reception.
Figure 110. LINSCI Interrupt routine
170/173
@interrupt void LINSCI_IT ( void ) /* LINSCI interrupt routine */
{
}
/* clear flags */
SCISR_buffer = SCISR;
SCIDR_buffer = SCIDR;
if ( SCISR_buffer & LHE )/* header error ? */
{
}
if (!LHLR)/* header time-out? */
{
}
{
}
if ( !(SCICR2 & RWU) )/* active mode ? */
SCISR;
SCIDR;/* Clear RDRF flag */
SCICR2 |= RWU;/* set mute mode */
SCISR;
SCIDR;/* Clear RDRF flag */
SCICR2 |= RWU;/* set mute mode */
_asm("rim");/* enable interrupts */
_asm("sim");/* disable interrupts */
Workaround
The problem can be detected in the LINSCI inter-
rupt routine. In case of timeout error (LHE is set
and LHLR is loaded with 00h), the software can
check the RWU bit in the SCICR2 register. If RWU
is cleared, it can be set by software. Refer to
ure
110. Workaround is shown in bold characters.
