7.2.7 UARTi transmit interrupt control and UARTi receive interrupt control registers

When using UARTi, 2 types of interrupts, which are UARTi transmit and UARTi receive interrupts, can be
used. Each interrupt has its corresponding interrupt control register. Figure 7.2.12 shows the structure of
UARTi transmit interrupt control and UARTi receive interrupt control registers.
For details about interrupts, refer to "Chapter 4. INTERRUPTS."
