Note: 1. If the pin-shared pin functions have multiple outputs simultaneously, the desired pin-shared
function is determined by the corresponding software control bits.
2. The OCDSDA and OCDSCK pins are supplied as OCDS dedicated pins and as such only
available for the HT45V6530 device which is the OCDS EV chip for the HT45F6530 device.
3. For less pin-count package types there will be unbonded pins which should be properly
configured to avoid unwanted current consumption resulting from floating input conditions.
Refer to the “Standby Current Considerations” and “Input/Output Ports” sections.
