Function
7 RTCOE Buffered SmaRTClock Output Enable.
Enables the buffered SmaRTClock oscillator output on P0.2.
0: Buffered SmaRTClock output not enabled.
1: Buffered SmaRTClock output is enabled.
6 WAKEOE Wakeup Request Output Enable.
Enables the Sleep Mode wake-up request signal on P0.3.
0: Wake-up request signal is not enabled.
1: Wake-up request signal is enabled.
5 MONDIS* POR Supply Monitor Disable.
Writing a 1 to this bit disables the POR supply monitor.
4:0 Unused Read = 00000b. Write = Don’t Care.
Notes:The POR Supply Monitor should not be disabled if the supply voltage is greater than 2.4 V. The lowest power
sleep mode current, 10 nA typical, can only be achieved when the supply voltage is less than 2.4 V. The
lowest power sleep mode for voltages above 2.4 V is 50 nA typical with the POR Supply Monitor enabled.
