This document is valid for the S12G96 and the S12G128 device. All information related to other devices is preliminary.
Characteristics noted under conditions 3.13V <= VDDA <= 5.5V>, -40˚C < Tj < 150˚C >, VRH=VDDA, VRL=VSSA
unless otherwise noted. Typical values noted reflect the approximate parameter mean at T
conditions unless otherwise noted.
Num
DRIVE bit = 1 is not recomended in this case.
DRIVE bit = 0 is not allowed with this high load.
