SCL clocks are showm identical for OD and PP

even though they differ substantially

= Active Drive by Master or Slave

= Open-Drain Pull-Up class by Master

= High-Z by Slave

Note: VDD: VDD1218_I3C

Note: Open-Drain: Master releases SDA after a suitable delay from SCL edges

Push-Pull: Master drives SDA after a suitable delay from SCL edges
