DAC range limited?
Quote:typically I can't get it below 150mV There is DAC linear output voltage range in 128A1U datasheet, which is in range of 0.15v to AVcc-0.15v.

Pin Inversion Works for Output, But Not Input
It may be useful to know that in the following code: PORTCFG.MPCMASK = PIN5_bm; PORTE.PIN0CTRL = PORT_ISC_LEVEL_gc; only PORTE.PIN5CTRL alters and PORTE.PIN0CTRL remains...
