USB (J8) Pinouts
A standard USB Type B connector was used to allow a USB cable to connect
the PICDEM™ USB to the PC. This is against the USB specification. Techni-
cally, only full speed devices are allowed to use the type B connector.

S1 - MCLR
Switch 1 is the MCLR line to the PIC16C745/765. This line resets the entire
system.
S2 - RA4
Switch 2 is connected to RA4. This is to allow a general purpose switch input
for code experiments. Debounce filtering is provided.
J3 - Bus/Self Power Selection
Jumper 3 switches the V
cable) to Self power (5V from the onboard regulator).
J9 - LED Enable
Some applications will want to use PORTB for some purpose other than driv-
ing the LED’s. By removing the jumper in J9, the LED’s will be disabled. The
default Chapter 9 firmware uses the LED’s to indicate activity at the different
stages of enumeration. To use this firmware mode, you should enable the
LED’s.
