ADC转换的触发点永不清零

初始信息：
. ADC扫描4个通道，一个具有单范围检测，2个DIF模式
由软件（ADCJSTARCONV…）触发的转换4个采样平均在所有通道上
在转换之间，使用API（EEPROMYORDION…）将Flash写入单个缓冲区（未禁用中断）
当进入内文阅读AdcSARSa SARIONITRYRG，并在结尾写Reg
经过几分钟的ADC执行触发中断（我可以聊天这一点）中断中断射击了。重置是必需的，故事重演。
转换的触发点是永不清零（根据TRM应该由硬件清除）。在运行期间没有修改内向量表。
我已经联系支持的情况下，但不动的东西了。
有什么想法吗？

  Initial info:
    . ADC scanns 4 channels, one with single range detect, 2 with dif mode
    .conversion triggered by software (ADC_startConv...) 4 sample averaging on all channels
    .between conversions flash is written using API (EEPROM_WRITE..) into a single buffer ( interrupts not disabled)
    .when entering intr read ADCSAR_SAR_INTR_REG, and written reg at the end
    After few minutes of adc performace triggering interrups ( I can chatch this point) the interrupts stop firing anymore. reset is required and story repeats.
    Conversion trigger bit is never cleared (acc. to TRM should be cleared by hardware). intr vector table is not modified during run.
    I'm already contacting support case, but does not move thing forward.
    Any ideas?
