18 / 148 page PIC12F683 DS41211B-page 16 Preliminary 2004 Microchip Technology Inc. 2.2.2.6 PCON Register The Power Control (PCON) register contains flag bits (see Table 12-2) to differentiate between a: • Power-on Reset (POR) • Brown-out Detect (BOD) • Watchdog Timer Reset (WDT) • External MCLR Reset The PCON register also controls the Ultra Low-Power Wake-up and software enable of the BOD. The PCON register bits are shown in Register 2-6. REGISTER 2-6: PCON – POWER CONTROL REGISTER (ADDRESS: 8Eh) U-0 U-0 R/W-0 R/W-1 U-0 U-0 R/W-0 R/W-x — — ULPWUE SBODEN — —POR BOD bit 7 bit 0 bit 7-6 Unimplemented: Read as ‘0’ bit 5 ULPWUE: Ultra Low-Power Wake-up Enable bit 1 = Ultra Low-Power Wake-up enabled 0 = Ultra Low-Power Wake-up disabled bit 4 SBODEN: Software BOD Enable bit(1) 1 = BOD enabled 0 = BOD disabled bit 3-2 Unimplemented: Read as ‘0’ bit 1 POR: Power-on Reset Status bit 1 = No Power-on Reset occurred 0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs) bit 0 BOD: Brown-out Detect Status bit 1 = No Brown-out Detect occurred 0 = A Brown-out Detect occurred (must be set in software after a Brown-out Detect occurs) Note 1: BODEN<1:0> = 01 in the Configuration Word register for this bit to control the BOD. Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ - n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown |
