Description
The mode is selected by changing the input level at this pin.
Low: Branch trace mode
High: RAM monitor mode
The input at this pin should be changed when AUDRST is low.
The AUD's internal buffers and logic are initialized by inputting a low level to
this pin. When this signal goes low, the AUD enters the reset state and the
AUD's internal buffers and logic are reset. When AUDRST goes high again
after the AUDMD level settles, the AUD starts operating in the selected mode.
