0: XTAL3 and XTAL4 in their normal configuration.
1: XTAL3 and XTAL4 internally shorted for use with Self Oscillate Mode.
Read = Varies. Software should not modify the value of these bits. To change the
RTC0PIN setting, the entire register contents should be read, modified, then rewritten.
LOADRDY
Automatic Load Capacitance Stepping Enable.
Enables/disables automatic load capacitance stepping.
0: Load capacitance stepping disabled.
1: Load capacitance stepping enabled.
Set by hardware when the load capacitance matches the programmed value.
0: Load capacitance is currently stepping.
1: Load capacitance has reached it programmed value.
Unused.
Read = 00b; Write = Don’t Care.
Load Capacitance Programmed Value.
Holds the user’s desired value of the load capacitance. See Table 20.2 on
page 196.
