14.3.10 UART Interrupt Status/Mask Registers
The UART interrupt status registers (UISRn), Figure 14-11, provide status for all potential
interrupt sources. UISRn contents are masked by UIMRn. If corresponding UISRn and
UIMRn bits are set, the internal interrupt output is asserted. If a UIMRn bit is cleared, the
state of the corresponding UISRn bit has no effect on the output.
Table 14-9 describes UISRn and UIMRn fields.
