Table 29-16. SCI Set Interrupt Register (SCISETINT) Field Descriptions (continued)
Bit Field Value Description
8 SET TX INT Set transmitter interrupt. This bit is effective in LIN or SCI-compatible mode. Setting this bit
enables the SCI/LIN to generate a transmit interrupt as data is being transferred from SCITD to
SCITXSHF and the TXRDY bit is being set.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
7 SET TOA3WUS INT Set timeout after three wakeup signals interrupt. This bit is effective in LIN mode only. Setting
this bit enables the SCI/LIN to generate an interrupt when a timeout occurs after three wakeup
signals have been sent.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
6 SET TOAWUS INT Set timeout after wakeup signal interrupt. This bit is effective in LIN mode only. Setting this bit
enables the SCI/LIN to generate an interrupt when a timeout occurs after one wakeup signal
has been sent.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
5 Reserved 0 Reads return 0. Writes have no effect.
4 SET TIMEOUT INT Set timeout interrupt. This bit is effective in LIN mode only. Setting this bit enables the SCI/LIN
to generate an interrupt when there is no LIN bus activity (bus idle) for at least four seconds.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
3-2 Reserved 0 Reads return 0. Writes have no effect.
1 SET WAKEUP INT Set wake-up interrupt. This bit is effective in LIN or SCI-compatible mode. Setting this bit
enables the SCI/LIN to generate a wakeup interrupt and thereby exit low-power mode. If
enabled, the wakeup interrupt is asserted when local low-power mode is requested while the
receiver is busy or if a low level is detected on the LINRX pin during low-power mode.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
0 SET BRKDT INT Set break-detect interrupt. This bit is effective in SCI-compatible mode only. Setting this bit
enables the SCI/LIN to generate an error interrupt if a break condition is detected on the LINRX
pin.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
