TMS320C28x Real-Time JTAG and Analysis

TMS320C28x Real-Time JTAG and Analysis
The F281x and C281x implement the standard IEEE 1149.1 JTAG interface. Additionally, the F281x and
C281x support real-time mode of operation whereby the contents of memory, peripheral, and register
locations can be modified while the processor is running and executing code and servicing interrupts. The
user can also single step through non-time critical code while enabling time-critical interrupts to be
serviced without interference. The F281x and C281x implement the real-time mode in hardware within the
CPU. This is a unique feature to the F281x and C281x, no software monitor is required. Additionally,
special analysis hardware is provided that allows the user to set hardware breakpoint or data/address
watch-points and generate various user selectable break events when a match occurs.
