Memory Card Interface mode: card socket configured to support memory cards. Dual-function
socket interface pins perform memory card-type interface functions.
I/O Card Interface mode: card socket configured to support I/O/memory card-type interface
functions. Dual-function socket interface pins perform I/O/memory card-type interface functions.
The RESET signal to the card socket is set active (high for normal, low for ATA mode).
The RESET signal to the card socket is set inactive (low for normal, high for ATA mode).
BVD1/-STSCHG pin is status change function.
BVD1/-STSCHG pin is ring indicate input pin from card.
