JTAG Test Access Port and OnCE Freescale Semiconductor, Inc. TME — Trace Mode Enable Bit TME enables trace operation. Test logic reset clears the TME bit. Trace operation is also affected by the SQC field. 1 = Trace operation enabled 0 = Trace operation disabled nc... Freescale Semiconductor, I FRZC — Freeze Control Bit This control bit is used in conjunction with memory breakpoint B registers to select between asserting a breakpoint condition when a memory breakpoint B occurs or freezing the PC FIFO from further updates when memory breakpoint B occurs while allowing the CPU to continue execution. The PC FIFO remains frozen until the FRZO bit in the OSR is cleared. 1 = Memory breakpoint B occurrence freezes PC FIFO and does not assert breakpoint condition. 0 = Memory breakpoint B occurrence asserts breakpoint condition. RCB and RCA — Memory Breakpoint B and A Range Control Bits RCB and RDA condition enabled memory breakpoint occurrences happen when memory breakpoint matches are either within or outside the range defined by memory base address and mask. 1 = Condition breakpoint on access outside of range 0 = Condition breakpoint on access within range BCB4–BCB0 and BCA4–BCA0 — Memory Breakpoint B and A Control Fields The BCB and BCA fields enable memory breakpoints and qualify the access attributes to select whether the breakpoint matches are recognized for read, write, or instruction fetch (program space) accesses. Test logic reset clears BCB4–BCB0 and BCA4–BCA0. Technical Data MMC2107 – Rev. 2.0 566 JTAG Test Access Port and OnCE MOTOROLA For More Information On This Product, Go to: www.freescale.com
