MPC5744P, "ADC0_WD_IRQn ",who knows the detailed description of it? thanks！
ADC0_EOC_IRQn = 496u, /**< ADC_0_EOC */ ADC0_ER_IRQn = 497u, /**< ADC_0_ER */ ADC0_WD_IRQn = 498u, /**< ADC_0_WD */
you can find more details in Reference manual - Chapter 36 (page 965+).
Basically - this interrupt occurs when pre-selected Hi or Lo value in ADC settings is exceeded.
Hope it helps.
Thank you very much. The problem has been solved
