SWO — Software Debug Occurrence Flag
TO — Trace Count Occurrence Flag
FRZO — FIFO Freeze Occurrence Flag
SQB — Sequential Breakpoint B Arm Occurrence Flag
SQA — Sequential Breakpoint A Arm Occurrence Flag
PM1 and PM0 — Processor Mode Field
SWO bit is set when the processor enters debug mode of operation
as a result of the execution of the BKPT instruction. This bit is cleared
on test logic reset or when debug mode is exited with the GO and EX
bits set.
TO is set when the trace counter reaches zero with the trace mode
enabled and the CPU enters debug mode. This bit is cleared on test
logic reset or when debug mode is exited with the GO and EX bits set.
FRZO is set when a FIFO freeze occurs. This bit is cleared on test
logic reset or when debug mode is exited with the GO and EX bits set.
SQB is set when sequential operation is enabled and a memory
breakpoint B event has occurred to enable trace counter operation.
This bit is cleared on test logic reset or when debug mode is exited
with the GO and EX bits set.
SQA is set when sequential operation is enabled and a memory
breakpoint A event has occurred to enable memory breakpoint B
operation. This bit is cleared on test logic reset or when debug mode
is exited with the GO and EX bits set.
These flags reflect the processor operating mode. They allow
coordination of the OnCE controller with the CPU for synchronization.
