1. SSTAT.5 = 0 selects combined Serial Port (UART) Tx and Rx interrupt; SSTAT.5 = 1 selects Serial Port Rx interrupt only
(Tx interrupt will be different, see Note 3 below).
2. This interrupt is used as Serial Port (UART) Tx interrupt if and only if SSTAT.5 = 1, and is disabled otherwise.
3. If SSTAT.0 = 1, the following Serial Port additional flag bits can cause this interrupt: FE, BR, OE
