Interrupts
Generic clock allocation
The generic clocks are allocated to different functions as shown in the “Generic Clock Allocation”
table in the SCIF Module Configuration section.
The SCIF has 14 interrupt sources:
The interrupt sources will generate an interrupt request if the corresponding bit in the Interrupt
Mask Register is set. The interrupt sources are ORed together to form one interrupt request. The
SCIF will generate an interrupt request if at least one of the bits in the Interrupt Mask Register
(IMR) is set. Bits in IMR are set by writing a one to the corresponding bit in the Interrupt Enable
Register (IER), and cleared by writing a one to the corresponding bit in the Interrupt Disable
Register (IDR). The interrupt request remains active until the corresponding bit in the Interrupt
