Bidirectional I/O lines. Software instructions determine the CMOS output or
Schmitt trigger input with pull-high resistor (determined by pull-high options:
nibble option). The PE2 is pin-shared with SDI. SDI is Serial interface serial
input.
Bidirectional I/O lines. Software instructions determine the CMOS output or
Schmitt trigger input with pull-high resistor (determined by pull-high options:
nibble option). The PE3 is pin-shared with SDO. SDO is a Serial interface
serial output.

ADC negative power supply, ground
Positive power supply
ADC positive power supply, AVDD should be externally connected to VDD.
OSC1 and OSC2 are connected to a 6MHz or 12MHz Crystal/resonator (de-
termined by software instructions) for the internal system clock.
3.3V regulator output.
UDP is USBD+ line
USB function is controlled by software control register.
UDN is USBD- line
USB function is controlled by software control register.
