使用 PCF2131TFY 的产品出现间歇性问题，一些板会在短短几天内耗尽电池电量。安装的电池为 CR2032。诊断这个问题有什么注意事项吗？这个部件是否存在已知问题？
结果发现问题出在所有印刷电路板上都有一些多余和未清除的助焊剂，导致电流过大和电池耗尽。
对于一些未使用的引脚，请按照以下建议进行设置：
客户在应用中不使用这些引脚时，可将 CLKOUT 和 TS1-4 引脚打开。
用户可通过设置 CLKOUT_ctl 寄存器（13h）的位[2:0] = 111b 将 CLKOUT 引脚设置为高 Z 模式。通过设置 Control_4 寄存器（03h）位 [7:4] = 0000b 和 Control_5 寄存器（04h）但 [7:4] = 0000b，将 TS1-4 引脚设置为非活动引脚。
