f_SWDCK
T_SWDI_setup SWDIO input setup before SWDCK high T = 1/f_SWDCK max
T_SWDI_hold
T_SWDO_valid SWDCK high to SWDIO output
T_SWDO_hold SWDIO output hold after SWDCK low
Notes
35. Based on device characterization (Not production tested).
36. f_TCK must also be no more than 1/3 CPU clock frequency.
37. f_SWDCK must also be no more than 1/3 CPU clock frequency.
38. SWV signal frequency and bit rate are limited by GPIO output frequency, see
