In the user manual for the LCD Control register (Rev 1.6, p791), it states that when LCDEN is set to 0, then LCDLP, and LCDFP are set low. When I probe these lines, they are high in the disabled state.
I have these pins both considered with:
- pulldown enabled
- pullup disabled
- input buffer enabled
- glitch filter disabled
- FP/LP functions selected.
There's nothing in the errata about these pins resetting to an incorrect state. Is there more information I'm missing, or is this an error in the documentation or chip?
