In either case, if Timer 2 is used to generate the baud rate, the TF2
interrupt flag does not occur. Therefore, Timer 2 interrupts do not
occur and do not have to be disabled. In this mode, the EXF2 flag
can, however, still cause interrupts that can be used as a third
external interrupt. Baud rate generation is described as part of the
UART serial port operation in the UART Serial Interface section.
