PROGRAM OR DEBUG SELECTION SWITCH (SW2)
The dsPIC30F2020 device program pins (PGC/PGD) are multiplexed with the UART
pins (U1RX and U1TX). A DIP switch (SW2) selects whether the default programming
pin pair (PGC/PGC) are used to program the device. Because PGC and PGD are
multiplexed with the UART pins, the pins can only be used to program the device.
Debugging is not possible with PGC/EMUC and PGD/EMUD.
When SW2 is in the PGM position, the PGC/PGD and PGC1/PGD1 pins are connected
to the ICD 2. This configuration allows you to program the device with either the default
programming pin pair (PGC/PGD) or the first set of auxiliary programming pins
(PGC1/PGD1). Emulation and debugging in not possible when SW2 is in the PGM
position and the default programming/emulation pins are selected (via the
Configuration bits).
When SW2 is in the DEBUG position, PGC1/EMUC1 and PGD1/EMUD1 must be
selected as the debugging pin pair in the Configuration bit settings window. Both
programming and debugging are possible in this configuration.
