@section USB RLINK based
Raisonance has an adapter called @b{RLink}. It exists in a stripped-down form on the STM32 Primer, permanently attached to the JTAG lines. It also exists on the STM32 Primer2, but that is wired for SWD and not JTAG, thus not supported.

m4_dnl Some macros to facilitate bit-banging delays.
m4_dnl There are 3 of them. One for self-contained delays, and two for those which must be split between setup and loop to keep from disturbing A at delay time.

m4_dnl This one is self-contained.

)')
m4_dnl These are the setup and loop parts of the split delay.
m4_dnl The argument passed to both must match for the result to make sense.
m4_dnl The setup does not figure into the delay. It takes 3 cycles when a loop is used and none if nops are used.

)')
m4_dnl These are utility macros for use with delays. Specifically, there is code below which needs some predictability in code size for relative jumps to reach. The m4_delay macro generates an extra NOP when an even delay is needed, and the m4_delay_loop macro generates an extra NOP when an odd delay is needed. Using this for the argument to the respective macro rounds up the argument so that the extra NOP will not be generated. There is also logic built in to cancel the rounding when the result is small enough that a loop would not be generated.
