each of which must be explicitly declared.
JTAG supports both debugging and boundary scan testing.
Flash programming support is built on top of debug support.
-@subsection SWD ransport
+@subsection SWD Transport
SWD (Serial Wire Debug) is an ARM-specific transport which exposes one
Debug Access Point (DAP, which must be explicitly declared.
(SWD uses fewer signal wires than JTAG.)
SWD is debug-oriented, and does not support boundary scan testing.
Flash programming support is built on top of debug support.
(Some processors support both JTAG and SWD.)
-@subsection SPI ransport
+@subsection SPI Transport
The Serial Peripheral Interface (SPI) is a general purpose transport
which uses four wire signaling. Some processors use it as part of a
solution for flash programming.
