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
Status Register (ISR) is cleared by writing a one to the corresponding bit in the Interrupt Clear
Register (ICR). Because all the interrupt sources are ORed together, the interrupt request from
the SCIF will remain active until all the bits in ISR are cleared.
