Bit 0  
DIS_PAC2  
When this bit is set to 1, it disables Port 2 address control  
and decoder.  
Bit 1  
EN_PAC2_MEM  
When this bit is set to 1, Memory Mode decoder is  
enabled. When it is cleared, the I/O Mode decoder is  
enabled.  
Bit 2  
Bit 3  
EN_PAC2_16  
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.  
READ_PROTECT  
Allows two cards at the same address to be read from.  
When this bit is set, it prevents the PCMCIA bus from  
becoming active.
