ISA-to-PC-Card (PCMCIA) Controllers PD6710/22  
Bit 4 I/O Window 1 Size  
0
1
8-bit data path to I/O Window 1.  
16-bit data path to I/O Window 1.  
When bit 5 below is 0, this bit determines the size of the data path to I/O Window 1. When bit 5 is  
1, this bit is ignored.  
Bit 5 Auto-Size I/O Window 1  
0
1
I/O Window 1 Size (see bit 4) determines the data path to I/O Window 1.  
The data path to I/O Window 1 will be determined based on -IOIS16 returned by the card.  
This bit determines the width of the data path to I/O Window 1. Note that when this bit is 1, the  
-IOIS16 signal (see Table 2 on page 20) determines the window size. This bit must be set for  
proper ATA mode operation (see ATA Mode Operationon page 88).
