Bit 12 (MS): Oscillator type selection.
0: RC type
1: XTAL type
Bit 11 (ENWDT): Watchdog Timer enabled.
0: Enable
1: Disable
Bit 10 (CLKS): Clocks of each instruction cycle.
0: Two clocks
1: Four clocks
Bit 9 (PTB): Protect bit.
0: Protect enabled
1: Protect disabled
Bit 8 (HLF): XTAL frequency selection.
0: Low frequency (32.768KHz)
1: High frequency
This bit is useful only when Bit 12 (MS) is 1. When MS is 0, HLF must be 0.
