Note. UART2 does not include the bit converter.
The interrupt vector and the interrupt control register are common to
the A-D conversion interrupt and UART2 transmit/receive interrupt.
It is switched by a selection of UART2 function as shown in Figure 37
and Table 5.
Figure 38 shows the connections of receiver/transmitter.
Figures 39 and 40 show the bit configuration of the UARTi transmit/
receive control register.
Each communication method is described below.
