BVD1/-STSCHG/-RI pin is status change function.
BVD1/-STSCHG/-RI pin is ring indicate input pin from card.
A transition (from high to low in Memory Card Interface mode or either high to low or low to high
in I/O Card Interface mode) on the BVD1/-STSCHG/-RI pin has not occurred since this register
was last read.
A transition on the BVD1/-STSCHG/-RI pin has occurred.
The RESET signal to the card socket is set active (high for normal, low for ATA mode).
