38 / 278 page ![]() PIC16(L)F1507 DS40001586D-page 38 2011-2015 Microchip Technology Inc. 4.2 Register Definitions: Configuration Words REGISTER 4-1: CONFIG1: CONFIGURATION WORD 1 U-1 U-1 R/P-1 R/P-1 R/P-1 U-1 — — CLKOUTEN BOREN<1:0>(1) — bit 13 bit 8 R/P-1 R/P-1 R/P-1 R/P-1 R/P-1 U-1 R/P-1 R/P-1 CP(2) MCLRE PWRTE WDTE<1:0> — FOSC<1:0> bit 7 bit 0 Legend: R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘1’ ‘0’ = Bit is cleared ‘1’ = Bit is set -n = Value when blank or after Bulk Erase bit 13-12 Unimplemented: Read as ‘1’ bit 11 CLKOUTEN: Clock Out Enable bit 1 = CLKOUT function is disabled. I/O function on the CLKOUT pin 0 = CLKOUT function is enabled on the 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 BORCON 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 WPUA3 bit. bit 5 PWRTE: Power-Up Timer Enable bit 1 = PWRT disabled 0 = PWRT enabled bit 4-3 WDTE<1:0>: Watchdog Timer Enable bits 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 Unimplemented: Read as ‘1’ bit 1-0 FOSC<1:0>: Oscillator Selection bits 11 = ECH: External Clock, High-Power mode: on CLKIN pin 10 = ECM: External Clock, Medium Power mode: on CLKIN pin 01 = ECL: External Clock, Low-Power mode: on CLKIN pin 00 = INTOSC oscillator: I/O function on CLKIN pin Note 1: Enabling Brown-out Reset does not automatically enable Power-up Timer. 2: Once enabled, code-protect can only be disabled by bulk erasing the device. |
