请问S08QGx空闲引脚什么模式功耗最低?
共6个寄存器,PTxD/PTxDD等。输入浮空不妥,输入接地? S08没用过,不过我用STM8,efm32,stm32等单片机都是要设置成输出。设置成输入功耗很大 yangsen 发表于 2016-6-12 17:58S08没用过,不过我用STM8,efm32,stm32等单片机都是要设置成输出。设置成输入功耗很大 ...
AN4441提到了类似的观点:
Tips and tricks to consider when designing for low power:
• Set the pins to a known state. For this family of devices—Never leave floating pins. Floating pins affect the overall
power consumption
但并没有提及用哪个模式。
