USB TAP Users Guide
Signal Requirement
Mnemonic
VDD Must be wired to the target. The USB TAP emulator uses this
signal to determine if power is applied to the target. The signal is
also used as a voltage reference for the signals driven by the
USB TAP emulator (BKPT, DSCLK, RESET, DSI, and TEA).
DSO Must be wired to the target processor. It is an input to the USB
TAP.
GND Must be wired to the target. GND is connected directly the USB
TAP ground inside the USB TAP.
PST3 Need not be wired to the target. The USB TAP does not
currently use this signal.
PST2 Need not be wired to the target. The USB TAP does not
currently use this signal.
PST1 Need not be wired to the target. The USB TAP does not
currently use this signal.
PST0 Need not be wired to the target. The USB TAP does not
currently use this signal.
DDATA3 Need not be wired to the target. The USB TAP does not
currently use this signal.
DDATA2 Need not be wired to the target. The USB TAP does not
currently use this signal.
DDATA1 Need not be wired to the target. The USB TAP does not
currently use this signal.
DDATA0 Need not be wired to the target. The USB TAP does not
currently use this signal.
GND Must be wired to the target. GND is connected directly the USB
TAP ground inside the USB TAP.
Reserved Need not be wired to the target. The USB TAP does not
currently use this signal.
Reserved Need not be wired to the target. The USB TAP does not
currently use this signal.
GND Must be wired to the target. GND is connected directly the USB
TAP ground inside the USB TAP.
