Macros
#define	SWDP_TRANSFER_ERROR BIT(3)
	Transfer or parity error detected during transaction.

SWD Packet Request Bits
Bit definitions for SWD packet request fields. These bits are used to construct the 8-bit request packet header sent during an SWD transaction.
#define	SWDP_REQUEST_APnDP BIT(0)
	Access Port (AP) or Debug Port (DP).
#define	SWDP_REQUEST_RnW BIT(1)
	Read (1) or Write (0) operation.
#define	SWDP_REQUEST_A2 BIT(2)
	Address bit 2 for register selection.
#define	SWDP_REQUEST_A3 BIT(3)
	Address bit 3 for register selection.

SWD Acknowledge (ACK) Response Bits
Bit definitions for SWD acknowledge response fields. These bits are used to indicate the result of an SWD transaction.
#define	SWDP_ACK_OK BIT(0)
	Transaction completed successfully.
#define	SWDP_ACK_WAIT BIT(1)
	Target requests to retry the transaction later.
#define	SWDP_ACK_FAULT BIT(2)
	Target detected a fault condition.

SWDP Interface Pin Definitions
Pin identifiers for SWDP interface control. These constants define bit positions for controlling individual pins in the SWDP interface.
#define	SWDP_SWCLK_PIN 0U
	Serial Wire Clock (SWCLK) pin identifier.
#define	SWDP_SWDIO_PIN 1U
	Serial Wire Data Input/Output (SWDIO) pin identifier.
#define	SWDP_nRESET_PIN 7U
	Active-low reset (nRESET) pin identifier.
