+@deffn {Interface Driver} {st-link}
+This is a driver that supports STMicroelectronics adapters ST-LINK/V2
+(from firmware V2J24) and STLINK-V3, thanks to a new API that provides
+directly access the arm ADIv5 DAP.
+
+The new API provide access to multiple AP on the same DAP, but the
+maximum number of the AP port is limited by the specific firmware version
+(e.g. firmware V2J29 has 3 as maximum AP number, while V2J32 has 8).
+An error is returned for any AP number above the maximum allowed value.
+
+@emph{Note:} Either these same adapters and their older versions are
+also supported by @ref{hla_interface, the hla interface driver}.
+
+@deffn {Config Command} {st-link serial} serial
+Specifies the serial number of the adapter.
+@end deffn
+
+@deffn {Config Command} {st-link vid_pid} [vid pid]+
+Pairs of vendor IDs and product IDs of the device.

+@deffn {Interface Driver} {xlnx_pcie_xvc}
+This driver supports the Xilinx Virtual Cable (XVC) over PCI Express.
+It is commonly found in Xilinx based PCI Express designs. It allows debugging
+fabric based JTAG devices such as Cortex-M1/M3 microcontrollers. Access to this is
+exposed via extended capability registers in the PCI Express configuration space.
+
+For more information see Xilinx PG245 (Section on From_PCIE_to_JTAG mode).
+
+@deffn {Config Command} {xlnx_pcie_xvc_config} device
+Specifies the PCI Express device via parameter @var{device} to use.
+
+The correct value for @var{device} can be obtained by looking at the output
+of lscpi -D (first column) for the corresponding device.
+
+The string will be of the format "DDDD:BB:SS.F" such as "0000:65:00.1".

@deffn {Flash Driver} stm32l4x
-All members of the STM32L4 microcontroller families from STMicroelectronics
+All members of the STM32L4 and STM32WB microcontroller families from STMicroelectronics
include internal flash and use ARM Cortex-M4 cores.
The driver automatically recognizes a number of these chips using
the chip identification register, and autoconfigures itself.
For example to read the FLASH_OPTR register:
@example
stm32l4x option_read 0 0x20
-# Option Register: <0x40022020> = 0xffeff8aa
+# Option Register (for STM32L4x): <0x40022020> = 0xffeff8aa
+# Option Register (for STM32WBx): <0x58004020> = ...
+# The correct flash base address will be used automatically
@end example
The above example will read out the FLASH_OPTR register which contains the RDP
