Power source voltage Vcc = –0.3 to 6.5 V
CNVss input voltage VI = –0.3 to Vcc +0.3 V
(2) The oscillation circuit constants of XIN-XOUT, XCIN-XCOUT may be some differences between 3850 group (standard) and 3850 group
(spec. H).
(3) Do not write any data to the reserved area and the reserved bit. (Do not change the contents after reset.)
