18.11 In-Circuit Debugger
When MPLAB
in-circuit debugging functionality is enabled. This func-
tion allows simple debugging functions when used with
MPLAB IDE. When the device has this feature enabled,
some of the resources are not available for general
use. These resources include the first 80 bytes of data
RAM and two I/O pins.
One of four pairs of Debug I/O pins may be selected by
the user using configuration options in MPLAB IDE.
These pin pairs are named EMUD/EMUC, EMUD1/
EMUC1 and EMUD2/EMUC2.
In each case, the selected EMUD pin is the Emulation/
Debug Data line, and the EMUC pin is the Emulation/
Debug Clock line. These pins will interface to the
MPLAB ICD 2 module available from Microchip. The
selected pair of Debug I/O pins is used by
MPLAB ICD 2 to send commands and receive
responses, as well as to send and receive data. To use
the in-circuit debugging function of the device, the
design must implement ICSP connections to MCLR,

dsPIC30F1010/202X
If EMUD/EMUC is selected as the debug I/O pin
pair, then only a 5-pin interface is required, as
the EMUD and EMUC pin functions are multi-
plexed with the PGD and PGC pin functions in
all dsPIC30F devices.
If
selected as the debug I/O pin pair, then a 7-pin
interface is required, as the EMUDx/EMUCx pin
functions (x = 1 or 2) are not multiplexed with the
PGD and PGC pin functions.
