If you're not debugging OpenOCD internals, or bringing up a
new JTAG adapter or a new type of TAP device (like a CPU or
JTAG router), you probably won't need to use these commands.
+In a debug session that doesn't use JTAG for its transport protocol,
+these commands are not available.
@deffn Command {drscan} tap [numbits value]+ [@option{-endstate} tap_state]
Loads the data register of @var{tap} with a series of bit fields
The Serial Vector Format, better known as @dfn{SVF}, is a
way to represent JTAG test patterns in text files.
+In a debug session using JTAG for its transport protocol,
OpenOCD supports running such test files.
@deffn Command {svf} filename [@option{quiet}]
The Xilinx Serial Vector Format, better known as @dfn{XSVF}, is a
binary representation of SVF which is optimized for use with
Xilinx devices.
+In a debug session using JTAG for its transport protocol,
OpenOCD supports running such test files.
