86 / 148 page  PIC12F683 DS41211B-page 84 Preliminary 2004 Microchip Technology Inc. TABLE 12-5: INITIALIZATION CONDITION FOR SPECIAL REGISTERS EECON1 9Ch ---- x000 ---- q000 ---- uuuu EECON2 9Dh ---- ---- ---- ---- ---- ---- ADRESL 9Eh xxxx xxxx uuuu uuuu uuuu uuuu ANSEL 9Fh 1111 1111 1111 1111 uuuu uuuu TABLE 12-4: INITIALIZATION CONDITION FOR REGISTERS (CONTINUED) Register Address Power-on Reset MCLR Reset WDT Reset Brown-out Detect(1) Wake-up from Sleep through Interrupt Wake-up from Sleep through WDT Time-out Legend: u = unchanged, x = unknown, — = unimplemented bit, reads as ‘0’, q = value depends on condition. Note 1: If VDD goes too low, Power-on Reset will be activated and registers will be affected differently. 2: One or more bits in INTCON and/or PIR1 will be affected (to cause wake-up). 3: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h). 4: See Table 12-5 for Reset value for specific condition. 5: If Reset was due to brown-out, then bit 0 = 0. All other Resets will cause bit 0 = u.
