Writing 0xE7 to this register forces XTAL3 and XTAL4 to be internally shorted for use
with Self Oscillate Mode.
Writing 0x67 returns XTAL3 and XTAL4 to their normal configuration.
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 203.
