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 need to be disabled. In this mode, the EXF2 flag

external interrupt. Baud rate generation is described as part of the
UART serial port operation in the UART Serial Interface section.
