19.1 PORT CONTROL DESCRIPTIONS

【原文】

PORT CONFIGURATION REGISTER (GPACON-GPJCON)

In S3C2440A, most of the pins are multiplexed pins. So, It is determined which function is selected for each pins.

The PnCON(port control register) determines which function is used for each pin.

If PE0 – PE7 is used for the wakeup signal in power down mode, these ports must be configured in interrupt mode.

【译文】

原文为在中断模式下配置,译文“这些端口必须配置为输入模式”与原文有出入,后续再行验证……
