2.5 Signal Descriptions
Table 2-3 specifies the signals on the F2812 device. All digital inputs are TTL-compatible. All outputs are
3.3 V with CMOS levels. Inputs are not 5 V tolerant. A 100 mA (or 20 mA) pullup/pulldown is used.

(1) 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.
(2) I = Input, O = Output, Z = High impedance
(3) PU = pin has internal pullup; PD = pin has internal pulldown
