29.7.3 SCI Set Interrupt Register (SCISETINT)
Figure 29-10 and Table 29-6 illustrate this register. SCISETINT register is used to enable the required
interrupts supported by the module.

Table 29-6. SCI Set Interrupt Register (SCISETINT) Field Descriptions
Bit Field Value Description
31-27 Reserved 0 Read returns 0. Writes have no effect.
26 SET FE INT Set framing-error interrupt. Setting this bit enables the SCI module to generate an interrupt
when a framing error occurs.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
25 SET OE INT Set overrun-error interrupt. Setting this bit enables the SCI module to generate an interrupt
when an overrun error occurs.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
24 SET PE INT Set parity interrupt. Setting this bit enables the SCI module to generate an interrupt when a
parity error occurs.
0 Read: The interrupt is disabled.
Write: No effect.
1 Read or write: The interrupt is enabled.
23-19 Reserved 0 Read returns 0. Writes have no effect.
18 SET RX DMA ALL Set receive DMA all. This bit determines if a separate interrupt is generated for the address
frames sent in multiprocessor communications. When this bit is 0, RX interrupt requests are
generated for address frames and DMA requests are generated for data frames. When this bit
is 1, RX DMA requests are generated for both address and data frames.
0 Read: The DMA request is disabled for address frames (the receive interrupt request is enabled
for address frames).
Write: No effect.
1 Read or write: The DMA request is enabled for address and data frames
17 SET RX DMA Set receiver DMA. To enable receiver DMA requests, this bit must be set. If it is cleared,
interrupt requests are generated depending on bit SCISETINT.
0 Read: The DMA request is disabled.
Write: No effect.
1 Read or write: The DMA request is enabled for address and data frames
