39 / 152 page  Atmel ATPL00B [datasheet] 43028A-ATPL - 9/12 39 Watchdog reset /EWDG signal and CONF(1)=CONF.RLT3. CONF.RLT3 = „0‟ : After a watchdog timeout, microcontroller starts execution from PC=0, but boot loader is not triggered. CONF.RLT3 = „1‟ : After a watchdog timeout, if field RLT3 in CONF SFR is „1', boot loader is triggered. The microcontroller keeps track of the start-up point in the AUX2 register Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 B it 0 AUX2 -- -- -- -- -- ST2 ST1 ST0 --: Reserved bits ST(2:0): Start-up flags “000”:Asynchronous external reset “001”:Software reset by writing AUX1(5)=‟1‟ “010”:Watchdog T3 timeout “100”:Asynchronous external reset SFR values after a reset are shown in Table 4-11. The internal RAM is not affected. Port registers are initialized to FFH to keep port pins in pull-up state. Table 4-11.
