CodeMaster OCD Driver
... is a software layer between the CodeMaster IDE and the JEM-52 emulator.
CodeMaster-52 includes several OCD (On-Chip Debug) drivers, each of which supports communications
to a particular target microcontroller family. CodeMaster-52 OCD drivers support "classical" JTAG, "2-wire JTAG"
and other JTAG-like and proprietary types of serial OCD interfaces. The
list of supported MCU families includes, but not limited to, Atmel AT89LP21x/4xx,
NXP P89LPC952/954, and Micronas HVCA microcontrollers.
