NOTES:
1. These bits are used in I
2. The BBS bit is set to 0 by writing a 0. Writing a 1 has no effect.
3. These bits are used in IE mode.
4. UART0: Timer A3 underflow signal, UART1: Timer A4 underflow signal,
5. The SCLKDIV bit is used in GCI mode.
6. Refer to the note for the SU1HIM bit in the UiSMR2 register.
UART2: Timer A0 underflow signal, UART3: Timer A3 underflow signal,
UART4: Timer A4 underflow signal.
