1. S0STAT.5 = 0 selects combined Serial Port 0 Tx and Rx interrupt; S0STAT.5 = 1 selects Serial Port 0 Rx interrupt only (and
TX interrupt will be different, see Note 3 below).
2. S1STAT.5 = 0 selects combined Serial Port 1 Tx and Rx interrupt; S1STAT.5 = 1 selects Serial Port 1 Rx interrupt only (and
TX interrupt will be different, see Note 4 below).
3. This interrupt is used as Serial Port 0 Tx interrupt if and only if S0STAT.5 = 1, and is disabled otherwise.
4. This interrupt is used as Serial Port 1 Tx interrupt if and only if S1STAT.5 = 1, and is disabled otherwise.
5. If S0STAT.0 = 1, the following Serial Port 0 additional flag bits can cause this interrupt: FE_0, BR_0, OE_0.
6. If S1STAT.0 = 1, the following Serial Port 1 additional flag bits can cause this interrupt: FE_1, BR_1, OE_1.
