Note: 1. The OCDSDA and OCDSCK pins are the OCDS dedicated pins and only available for the BS66V3x0 device
which is the OCDS EV chip for the BS66F3x0 device.
2. For less pin-count package types there will be unbonded pins which should be properly congured to
avoid unwanted current consumption resulting from floating input conditions. Refer to the “Standby
Current Considerations” and “Input/Output Ports” sections.
