16.5.5
This section describes bus operation during read, write, and interrupt acknowledge cycles to the UART
module.
16.5.5.1
The UART module responds to reads with byte data. Reserved registers return zeros.
16.5.5.2
The UART module accepts write data as bytes. Write cycles to read-only or reserved registers complete
normally without exception processing, but data is ignored.
16.5.5.3
An internal interrupt request signal notifies the interrupt controller of any unmasked interrupt conditions.
The interrupt priority level is programmed in ICR2.
