REGISTER 4-1: CONFIG1: CONFIGURATION WORD 1 (CONTINUED)
bit 2-0
FOSC<2:0>: Oscillator Selection bits
111 = ECH: External clock, High-Power mode: on CLKIN pin
110 = ECM: External clock, Medium-Power mode: on CLKIN pin
101 = ECL: External clock, Low-Power mode: on CLKIN pin
100 = INTOSC oscillator: I/O function on OSC1 pin
011 = EXTRC oscillator: RC function connected to CLKIN pin
010 = HS oscillator: High-speed crystal/resonator on OSC1 and OSC2 pins
001 = XT oscillator: Crystal/resonator on OSC1 and OSC2 pins
000 = LP oscillator: Low-power crystal on OSC1 and OSC2 pins
Note 1: Enabling Brown-out Reset does not automatically enable Power-up Timer.
2: Once enabled (CP = 0), code-protect can only be disabled by bulk erasing the device.
