  • Hi Sir Yes, the GPIOs can all be programmed to set pull-up or pull-down. Yes, all GPIOs have interrupt functionality. For unused GPIO pins, they are left floating in the HW design by default and configured as input mode in the FW settings.

  • Hi Kaiser 我們電路上使用的型號是CM2012H32768DZFT , ±20ppm 12.5pF CL使用12pF也是可起振。 貴司使用的Crystal型號是CITIZEN的CM315D32768DZFT, +/-20ppm, CL=12.5pF 但CL卻使用20pF，這樣應該會振不起來 可試者改12pF後開機量測一下波形確認是否有正常起振
