FCKSM<1:0>
Unimplemented: Read as ‘0’
FCKSM<1:0>: Clock Switching and Monitor Selection Configuration bits
1x = Clock switching is disabled, fail-safe clock monitor is disabled
01 = Clock switching is enabled, fail-safe clock monitor is disabled
00 = Clock switching is enabled, fail-safe clock monitor is enabled
FRANGE: Frequency Range Select for FRC and PLL bit
Acts like a “Gear Shift” feature that enables the dsPIC DSC device to operate at reduced MIPS at a
reduced supply voltage (3.3V)
FRANGE
Bit Value
1 = High Range
0 = Low Range
Unimplemented: Read as ‘0’
OSCIOFNC: OSC2 Pin I/O Enable bit
1 = CLKO output signal active on the OSCO pin
0 = CLKO output disabled
POSCMD<1:0>: Primary Oscillator Mode
11 = Primary Oscillator Disabled
10 = HS oscillator mode selected
01 = Reserved
00 = External clock mode selected
