5.3 Power and Ground Detection
Two test points are provided on some device adapters
for the following: GND (black) and VCCME (red).
On certain Device Adapters, to visually indicate Target
Power mode, the “target power” LED will illuminate”
5.4 Specific Device Adapter Issues
This section details processor-specific considerations
that have been made on device adapters. Only
adapters with special considerations are listed.
5.4.1 DVA12XP080
5.4.2 DVA12XP081
This device adapter is intended for use with PIC12C50X
8-pin DIP devices. It has four mechanical switches that
allow target pins GP2 to GP5 to be routed to the emulator
silicon on the PCM16XA0 processor module or the
oscillator chip on the device adapter, as shown in Table 5-1.
In addition, a 24C00 EEPROM (U1) is connected to
RA0 and RA1 of the emulator silicon to support the
EEPROM capabilities of the PIC12CE51X family devices.
For information on how to use EEPROM memory, see the
MPLAB IDE on-line device-specific limitations for the
PCM16XA0 (PIC12CE518/519) devices by selecting
Debugger>Settings
, clicking the Limitations tab, and then
clicking the Details button.

This device adapter is intended for use with PIC12C67X
8-pin DIP devices. It has two mechanical switches that
allow target pins GP4 and GP5 to be routed to the emulator
silicon on the PCM12XA0 processor module or the
oscillator device on the device adapter, as shown in
Table 5-2.
