<parameters> describing a system level TAP “MultiTap”
A “Multitap” is a system level or chip level test access port (TAP) in a JTAG scan chain. It can for example
provide functions to re-configure the JTAG chain or view and control power, clock, reset and security of
different chip components.
At the moment the debugger supports three types and its different versions:
Icepickx, STCLTAPx, MSMTAP:
Example
:
DAPTAP
<tap>
Specifies the TAP number which needs to be activated to get the
DAP TAP in the JTAG chain.
Used if MULTITAP=Icepickx.
DEBUGTAP
<tap>
Specifies the TAP number which needs to be activated to get the
core TAP in the JTAG chain. E.g. ARM11 TAP if you intend to
debug an ARM11.
Used if MULTITAP=Icepickx.
ETBTAP
<tap>
Specifies the TAP number which needs to be activated to get the
ETB TAP in the JTAG chain.
