Oscillator Control Registers
Duplicate frequency derived from HFINTOSC.
SPLLEN: Software PLL Enable bit
If PLLEN in Configuration Word 1 = 1:
SPLLEN bit is ignored. 4x PLL is always enabled (subject to oscillator requirements)
If PLLEN in Configuration Word 1 = 0:
1 = 4x PLL Is enabled
0 = 4x PLL is disabled
