void(* | read_reg )(uint8_t cmd, uint32_t *value, uint32_t ap_delay_hint) |
Queued read of an AP or DP register. More... | |
int(* | run )(void) |
Execute any queued transactions and collect the result. More... | |
int(* | switch_seq )(enum swd_special_seq seq) |
Queue a special SWDIO sequence. More... | |
int *(* | trace )(bool swo) |
Configures data collection from the Single-wire trace (SWO) signal. More... | |
void(* | write_reg )(uint8_t cmd, uint32_t value, uint32_t ap_delay_hint) |

int(* swd_driver::init) (void) |
Initialize the debug link so it can perform SWD operations.
As an example, this would switch a dual-mode debug adapter into SWD mode and out of JTAG mode.

void(* swd_driver::read_reg) (uint8_t cmd, uint32_t *value, uint32_t ap_delay_hint) |
Queued read of an AP or DP register.
Command | byte with APnDP/RnW/addr/parity bits |
Where | to store value to read from register |
ap_delay_hint | Number of idle cycles that may be needed after an AP access to avoid WAITs |

int*(* swd_driver::trace) (bool swo) |
Configures data collection from the Single-wire trace (SWO) signal.
swo | true if SWO data collection should be routed. |
For example, some debug adapters include a UART which is normally connected to a microcontroller's UART TX, but which may instead be connected to SWO for use in collecting ITM (and possibly ETM) trace data.
void(* swd_driver::write_reg) (uint8_t cmd, uint32_t value, uint32_t ap_delay_hint) |
Queued write of an AP or DP register.
Command | byte with APnDP/RnW/addr/parity bits |
Value | to be written to the register |
ap_delay_hint | Number of idle cycles that may be needed after an AP access to avoid WAITs |
