12.4 EMULATOR POD
The emulator pod (DV244005) consists of a main board enclosed in the casing with a
port for either of two driver boards (for standard or high-speed communication with a
target). On the emulator encloser are push buttons, indicator lights (LEDs) and a logic
probe connector interface.
12.4.1 Main Board
This component has an interface processor (dsPIC DSC), a USB 2.0 interface capable
of USB speeds of 480 Mb/sec, a Field Programmable Gate Array (FPGA) for general
system control and increased communication throughput, an SRAM for holding the pro-
gram code image for programming into the emulation device on-board Flash, the exter-
nal trigger logic, user interface push buttons and LED indicators.
The MPLAB REAL ICE in-circuit emulator system supports two types of interfaces to
the target processor. They consist of the standard driver board and an optional
high-speed driver board. These boards are inserted into the emulator pod via a card
guide.
Durability/insertion life cycle of the card guide: 10,000 cycles
12.4.2 Push Buttons
The push buttons have the following significance.
12.4.3 Indicator Lights (LEDs)
The indicator lights have the following significance.

12.4.4 Logic Probe/External Trigger Interface
Probes can be connected to the 14-pin header on the side of the unit for processing
external signals that are used for triggering external equipment. This header contains
8 input/output connections that are user selectable as inputs or outputs with logic levels
that are proportional to the target operating voltage.
The outputs can be used for triggering an external logic analyzer or oscilloscope to
allow the developer to capture events of interest based on trigger criteria set within
MPLAB IDE. The external trigger is a pulse of approximately 1.5 s. This value is not
determinsitic and the external tool should be triggered on a pulse edge.
The inputs are part of a trigger bus.
