UART Modules
26.3.10 UART Interrupt Status/Mask Registers (UISRn/UIMRn)
The UISRs, shown in
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.
The UISRn and UIMRn registers share the same space in memory. Reading this register provides
the user with interrupt status, while writing controls the mask bits.
