Note:
The JTAG connector X701 only populates phyCORE-LPC2292/94
modules with order code PCM-023-D. This version of the phyCORE
module is included in all Rapid Development Kits (order code
KPCM-023). JTAG connector X701 is not populated on phyCORE
modules with order code PCM-014 that are intended for OEM
implementation. However, all JTAG signals are also accessible at the
phyCORE-connector X1 (Molex connectors). We recommend
integration of a standard (2.54 mm pitch) pin header connector in the
user target circuitry to allow easy program updates via the JTAG
interface.
See Table 74 for details on the JTAG signal pin assignment.
PHYTEC offers a JTAG-Emulator adapter (order code JA-002) for
connecting the phyCORE-LPC2292/94 to a standard emulator. The
JTAG-Emulator adapter extends the signals of the module's JTAG
connector to a standard ARM connector with 2.54 mm pin pitch. The
JA-002 therefore functions as an adapter for connecting the module's
non-ARM-compatible JTAG connector X701 to standard Emulator
connectors.
