JTAG connector
Programming/debugging of module can be done through JTAG interface.
JTAG is a four-lead interface permitting the takeover of control over the processor’s core. The possibilities
offered by this interface are, among others: step operation, full-speed operation, hardware and software
breakpoints, inspection and modification of contents of registers and data memories.
EVBlpc213x board has standard, 20-pin connector, allowing operation with all JTAG debuggers.
