S32k144 MCAL 硬件触发adc DMA传输时，dma只能进一次中断

[kun0o0]

MCAL库：S32K14X_MCAL4_2_RTM_1_0_0

在使用adc采样时，使用PDB硬件触发，无法连续采样（只获取了一次adc数据），debug发现只进了一次MCL_DMA_CH_0_ISR中断服务函数；

Hi @kun0o0,

Please refer to the following example: Example S32K144 PDB ADC trigger DMA ISR S32DS - NXP Community. It showcases how to use the back-to-back mode of the PDB to trigger the sequence of ADC conversion.

Best regards,
Julián
