Nl PXI-4071数据采集器 数字万用表

PXI-4071要使用此睡眠模式，请将SM[2，0]位写入“001”。该模式停止CPU，但允许ADC、外部中断、USART、双线串行接口、看门狗和计数器工作。ADC降噪模式基本上停止了CLK中央处理器，CLK我/o还有CLKz比。我们可以从唤醒控制器ADC噪声降低模式通过以下方法:

外部复位
看门狗系统复位·看门狗中断·掉电复位
双线串行接口地址匹配
 INT上的外部电平中断
引脚变化中断
定时器计数器中断
SPM/EEPROM就绪中断

PXI-4071 To use this sleep mode, write the SM[2,0] bit to "001". This mode stops the CPU but allows the ADC, external interrupts, USART, two-wire serial interface, watchdog, and counter to work. The ADC noise reduction mode basically stops the CLK CPU, CLK me /o, and CLKz ratio. We can reduce noise mode from the wake controller ADC by the following methods:

External reset
Watchdog system reset · Watchdog interruption · Power failure reset
Two-wire serial interface address matching
External level interrupt on INT
Pin change interrupt
Timer counter interrupt
SPM/EEPROM ready interrupt
