FOSC0 External oscillator configuration (valid when IRC = 1):
000b = LP1 – low power crystal (32KHz)
001b = LP2 – low power crystal (32KHz - 1MHz)
010b = XT1 – normal crystal (32KHz - 8MHz)
011b = XT2 – normal crystal (1MHz - 24MHz)
100b = HS1 – high speed crystal (1MHz - 32MHz)
101b = HS2 – high speed crystal (1MHz - 50MHz)
110b = HS3 – high speed crystal (1MHz - 100MHz)
111b = RC network - OSC2 is pulled high by a weak pullup (no CLKOUT out-
put)
