64. ty of the povver on reset logic changes vvith each revision of the MPC823 For your purposes this means that you may need to select a different source to generate a povver on reset To select your povver on reset source you need to set Ji on the MPC823ADS daughterboard When the J1 jumper is between positions 1 and 2 a power on reset is generated by the keep alive power rail KAPWR For example when KAPWR goes below 2 005V a power on reset is generated When the J1 jumper is between positions 2 and 3 a power on reset is generated from the main 3 3V power rail In other words when the 3 3V power rail gets below 2 805V a power on reset is generated 1 LX 1 E E XKX KEEP ALIVE POWER RAIL MAIN POWER RAIL Figure 2 3 Power On Reset Source 2 1 3 Selecting the VDDL Source The J3 jumper is used to select the VDDL which supplies the MPC823 s internal logic When the J3 jumper is between positions 1and 2 VDDL is supplied with 3 3V of power When the J3 jumper is between positions 2 and 3 VDDL is supplied with 2 2V of power The J3 jumper is factory set between positions 1 and 2 J3 SIX X34 3 3V VDDL 2V VDDL Figure 2 4 VDDL Source 2 4 MPC823ADSDB USER S MANUAL MOTOROLA For More Information On This Product Go to www freescale com Freescale Semiconductor Inc Configur
