17.2.1 Pin Descriptions
Pins Used in Both Modes
Pin
AUDMD
AUDRST
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. When no
connection is made, this pin is pulled up internally.
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. When no
connection is made, this pin is pulled down internally.
