#117048 - SILabs analog inouts Responding to: ???'s previous message |
I am using only 1 analog input(P0.7).
I guess they have kept this for the f3xx deviates as well (check): (from f12x datasheet) "Configuring a Port pin as an analog input: 1. Disables the digital input path from the pin. This prevents additional power supply current from being drawn when the voltage at the pin is near VDD / 2. A read of the Port Data bit will return a logic 0 regardless of the voltage at the Port pin. 2. Disables the weak pullup device on the pin. Erik |

| Thanks | 01/01/70 00:00 | |
| and see the chip go POOF | 01/01/70 00:00 | |

| disable weak pull-up for P0.7 only??? | 01/01/70 00:00 | |
| simply specify it analog | 01/01/70 00:00 | |
Specify as analog and P0SKIP | 01/01/70 00:00 |
