Thanks for the earlier support..


i am using MC9S12Z. micro, on my application i have configured the BATS module for generating low voltage interrupt. i have configured Low Voltage Warning (LBI 1).. At 25 deg ambient temperature it was working as defined in datasheet voltage level but if kept the micro in -40 deg c, voltage level will be vary around 0.2 to 0.4V. let me know, this is the intended behavior for at -40 deg c. 


example: at 25 deg, BATS interrupt occurs within the defined range in datasheet 

                at -40 deg BATS interrupt occurs 0.2  to 0.4V for defined range. 


Please need some support on this..
