Note: 1. If the pin-shared pin functions have multiple outputs, the desired pin-shared function is
determined by the corresponding software control bits.
2. The OCDSDA and OCDSCK pins are used as the OCDS dedicated pins and only available
for the BC68V2123 device which is the OCDS EV chip of the BC68F2123.
