| 2. | If rosc pin series a resister to vdd , or connect a capacitor to vss , the switching frequency can be adjusted
切换频率是由osc频率决定，以rosc脚串联电阻到vdd ，可调整切换频率，电阻值减少，频率增加。 |
| 3. | If rosc pin connect a resister to vdd , the switching frequency can be adjusted ; the value of resister decreases , the frequency will go higher
切换频率是由osc频率决定，以rosc脚串联电阻到vdd ，可调整切换频率，电阻值减少，频率会增加。 |
| 4. | The switching frequency is decided by osci frequency . if rosc pin series a resister to vdd , or connect a capacitor to vss , the switching frequency can be adjusted
切换频率是由osc频率决定，以rosc脚串联电阻到vdd ，或串联电容到vss ，可调整切换频率。 |
| 5. | And agmatine also decreased apa , vmax ) v dd , rpf and apd50 , 9o in a concentration - dependent manner in human atrial fibers and guinea pig papillary muscles
胍丁胺还可浓度依赖地缩短离体豚鼠乳头肌与人心房纤维的动作电位的时程，抑制v _ ( max )和降低vdd和rpf 。 |
| 6. | St1689e has build - in switching frequency but can be decreased by connecting a cap . to osci . if rosc pin connect a resister to vdd , the switching frequency can be increased
St1689已内建切换频率，但接电容到osci可降低之，以rosc脚串联电阻到vdd ，则切换频率增加。 |
| 7. | St1688nd has build - in switching frequency but can be decreased by connecting a cap . to osci . if rosc pin connect a resister to vdd , the switching frequency can be increased
St1688已内建切换频率，但接电容到osci可降低之，以rosc脚串联电阻到vdd ，则切换频率增加。 |
| 8. | Vdd relies on the i / o permission mask to trap port access , and it essentially simulates the operation of hardware for the benefit of applications that were originally programmed to talk directly to hardware on a bare machine
一个vdd依赖于一个i / o许可程序来限制端口访问，并且它本来（是要）效仿硬件的操作，来帮助应用在一个裸机上同硬件直接对话的最初操作。 |
| 9. | A vdd relies on the i / o permission mask to trap port access , and it essentially simulates the operation of hardware for the benefit of applications that were originally programmed to talk directly to hardware on a bare machine
一个vdd依赖于一个i / o许可程序来限制端口访问，并且它本来（是要）效仿硬件的操作，来帮助应用在一个裸机上同硬件直接对话的最初操作。 |
| 10. | So we recommend that you connect any unused input terminal to vdd or vss , do not input any signals before power is turned on and ground your body , work assembly table and assembly equipment to protect against static electricity
因此请勿将任何未用的输入端接到vdd或vss ，不要在电源打开之前向模块输入任何信号，并将操作者的身体工作台装配台接地，安装设备需防止静电。 |
