loading
- - 0.4 V
Note
1. With Minimal IoL/IoH driving capability loading, IO is garanteed to meet Vol < 0.4V or VOH >
(VDDIO-0.5V) spec.
2. Maximal GPIO loading is 6mA for application such as driving LED, which does not care
about Vol/Voh spec. Please set DS=3 for such application.
3. VDD18_AO_XTAL supplies power to IOVREF.
4. Do not use this setting, it’s too weak for most applications.
5. Test condition: GPIO pin voltage close to 0V.
6. Test condition: GPIO pin voltage close to VDDIO(3.3V).
