H), and 3850 group (spec. A) (1) The absolute maximum ratings of 3850 group (spec. H/A) is smaller than that of 3850 group (standard). •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 among 3850 group (standard), 3850 group (spec. H), and 3850 group (spec. A). (3) Do not write any data to the reserved area and the reserved bit. (Do not change the contents after reset.) (4) Fix bit 3 of the CPU mode register to “1”. (5) Be sure to perform the termination of unused pins. |
