Description
LSB range Address for Port 1
Description
When this bit is set to 1, it disables Port 2 address control
and decoder.
When this bit is set to 1, Memory Mode decoder is
enabled. When it is cleared, the I/O Mode decoder is
enabled.
When this bit is set, data swapping is provided internal to
the chip during data reads from the low byte of the ATA
bus to the PCMCIA bus high byte, and from the high byte
of the PCMCIA bus to the low byte of the ATA bus during
data writes. When this bit is cleared, it is high byte to high
byte and low byte to low byte.
Allows two cards at the same address to be read from.
When this bit is set, it prevents the PCMCIA bus from
becoming active.
