R/W Window B Data Trace Function
Setting these bits enables AUD to trace memory
access in the area designated by window B. Read
access, write access, or both can be designated as
tracing conditions. WE also designates whether the I
bus or the L bus should be traced. For details, see
section 23.3.7, AUD Extended Control Register
(AUECSR).
00: Disables window B data trace function
01: Traces only write access
10: Traces only read access
11: Traces both read and write accesses

R/W Trace Mode
Designates CPU operation when the FIFO buffer for
storing various trace data in AUD becomes full.
0: Full trace mode (outputs all generated trace).
1: Real-time trace mode (outputs trace data in real-
time without stopping CPU).

R/W AUD Enable
Setting this bit enables AUD to select the trace
function designated by the bits BRE, BR, WA0, WA1,
WB0, and WB1. When this bit is 0, the tracing
designated by BRE, BR, WA0, WA1, WB0, and WB1 is
not executed.
0: Disables AUD trace function
1: Enables AUD trace function
