ME0 MCAL低功耗流程分享

[Ekko]

GPIO

建议空闲IO配置成输出低电平，如果IO口过多，可以重新通过YCT新建工程，配置低功耗下专门IO状态，在进入低功耗前，重新Port_Init()

ADC

Adc_StopGroupConversion(AdcConf_AdcConfigSet_AdcGroup_0);
Adc_DeInit();

GPT

Gpt_DeInit();

LIN

Lin_GoToSleepInternal(LinConf_LinChannel_LINFlexD0);
Lin_DeInit();

CAN

Can_SetControllerMode(CanConf_CanController_CAN_0, CAN_CS_STOPPED);
Can_DeInit();

I2C

I2C参考demo例程，必须等待状态完成，才能Deinit成功。

do
{
   TempRav = CddI2c_GetTransferStatus(CddI2cConf_I2cChannel_I2cChannel_0);
} while (I2C_CHN_COMPLETED != TempRav);

CddI2c_DeInit();

SPI

Spi_Cancel(SpiConf_SpiChannel_Spi1MasteChannel0);
Spi_DeInit();

UART

CddUart_Abort(CDDUART_Channel_0,CDDUART_RECEIVE);
CddUart_Abort(CDDUART_Channel_0,CDDUART_SEND);
CddUart_Deinit();

DMA

建议DMA最后关闭，之后再关闭相关外设中断。

CddDma_DeInit();

低功耗异常排查建议

通过*Det_ReportError()*返回状态确定外设是否Deinit成功
