    I don't find any information about code on this model
    the code is in M30833FJ,EEprom: 93C76 just for counter
    The M32C/83 RENISAS Group (M32C/83, M32C/83T) microcomputer is a single-chip control unit that utilizes highperformance
    silicon gate CMOS technology with the M32C/80 Series CPU core.

    so we need programmer for it

    please upload good and tested shematic interface

    i think M30833FJ need more than RX TX,here is Target interface to M16C62/M16C80/M32C (M30624/M30625/M30800)
    VCCS Positive supply voltage of target
    BUSY Target CPU Busy signal output.
    SCLK Target CPU Serial clock (input)
    EPM EPM signal of target CPU
    GND Common signal ground
    RESET RESET signal of target system
    CNVss Target CPU CNVss signal
    TxD Target CPU Serial data output
