Advance Information DS41620C-page 9 PIC16(L)F145X REGISTER 3-3: CONFIGURATION WORD 1 R/P-1 R/P-1 R/P-1 R/P-1 R/P-1 U-1 FCMEN IESO CLKOUTEN BOREN<1:0> — bit 13 bit 8 R/P-1 R/P-1 R/P-1 R/P-1 R/P-1 R/P-1 R/P-1 R/P-1 CP MCLRE PWRTE WDTE<1:0> FOSC<2:0> bit 7 bit 0 Legend: R = Readable bit P = Programmable Bit U = Unimplemented bit -n = Value after Bulk Erase ‘1’ = Bit is set ‘0’ = Bit is cleared bit 13 FCMEN: Fail-Safe Clock Monitor Enable bit 1 = Fail-Safe Clock Monitor is enabled 0 = Fail-Safe Clock Monitor is disabled bit 12 IESO: Internal/External Switchover bit 1 = Internal/External Switchover mode is enabled 0 = Internal/External Switchover mode is disabled bit 11 CLKOUTEN: Clock Out Enable bit 1 = CLKOUT function is disabled. I/O or oscillator function on CLKOUT pin. 0 = CLKOUT function is enabled on CLKOUT pin bit 10-9 BOREN<1:0>: Brown-out Reset Enable bits(1) 11 = BOR enabled 10 = BOR enabled during operation and disabled in Sleep 01 = BOR controlled by SBOREN bit of the PCON register 00 = BOR disabled bit 8 Unimplemented: Read as ‘1’ bit 7 CP: Code Protection bit(2) 1 = Program memory code protection is disabled 0 = Program memory code protection is enabled bit 6 MCLRE: MCLR/VPP Pin Function Select bit If LVP bit = 1: This bit is ignored. If LVP bit = 0: 1 =MCLR/VPP pin function is MCLR; Weak pull-up enabled. 0 =MCLR/VPP pin function is digital input; MCLR internally disabled; Weak pull-up under control of WPUA register. bit 5 PWRTE: Power-up Timer Enable bit(1) 1 = PWRT disabled 0 = PWRT enabled bit 4-3 WDTE<1:0>: Watchdog Timer Enable bit 11 = WDT enabled 10 = WDT enabled while running and disabled in Sleep 01 = WDT controlled by the SWDTEN bit in the WDTCON register 00 = WDT disabled 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 on 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 protection can only be disabled by bulk erasing the device. |
