Extended Data
The data in this register allows the registers indicated by the Extended Index register to be read
and written. The value of this register is the value of the register selected by the Extended Index
register.

Extension Control 1
Bit 0: VCC Power Lock
This bit can be used to prevent card drivers from overriding the Socket Services’ task of controlling
power to the card, thus preventing situations where cards are powered incorrectly.
