RE:关于MC9S08LG32, reset pin as bi-directional reset and LCD pins as open-drain G
When using reset pin as bi-directional reset and LCD pins as open-drain GPIO,the internal pullups are not disable when these pins are used in output mode.This can cause some current leakage through the pads if zero is driven.This is also true for stop 2 mode.
当复位引脚作为双向复位功能使,或当LCD管脚作为开漏GPIO, 这些引脚作为输出时有内部上拉. 在输出低的情况下, 这会引起漏电流(注: 因为有电流从电源通过上拉电阻到低电平). 在stop2模式下, 也同样成立. |
