TI工程师你好:
drv8880由其他模式切换到ATE调谐模式,只需要将ATE(自动调谐)置为高电平吗? 这时候DECAY0/DECAY1电平状态依然保持,芯片已那个信号为准,这ATE与DECAY那个优先级高??
To enable the AutoTune mode, pull the ATE pin logic high. Ensure the DECAYx pins are logic low. The
AutoTune mode is registered internally when exiting from sleep mode or the power-up sequence. The ATE pin
can be shorted to V3P3 to pull it logic high for this purpose.
但实际当中,是ATE的优先级高
The AutoTune mode is registered internally when exiting from sleep mode or the power-up sequence.
建议更改设置后,重新上电,或者执行一次休眠到唤醒。
