I/O
ADC Voltage Reference Output (2 V). Requires a low ESR
(50 m

ground. (Can accept external reference input (2 V) if the
software bit is enabled for this mode. 110

Typical drive strength of the output buffer for all pins is 4 mA except for TDO, XCLKOUT, XF, XINTF, EMU0, and EMU1 pins, which are 8 mA.
I = Input, O = Output, Z = High impedance
§ PU = pin has internal pullup; PD = pin has internal pulldown. Pullup/pulldown strength is given in Section 6.3.
