1. Viewed from the MCU.
2. The connector locking mechanism provides additional ground connections on each end of the connector.
3. This is an output from the connector standpoint. It may or may not be from the MCU.
4. No connection — should be left open. Reserved for MDO16 on devices with more than sixteen MDO signals (future
compatibility). In some applications this may be used as an SRAM voltage detect to determine when voltage for a standby
SRAM is disconnected.
