PCMCIA Host Write  
PC_DATA<7–0> (Even Byte) written to ATA_DATA<7–0>  
PC_DATA<15–8> (Odd Byte) written to ATA_DATA<7–0>  
PCMCIA Host Read  
The PCMCIA selects an even address, then the ZX6017 pulls WAIT  
and reads the even register from the peripheral device, saves it in a  
latch, increments the local peripherals address bus, then reads the odd  
data byte and clears the PCMCIA WAIT pin.  
ATA_DATA<7–0> (Even Byte) put onto PC_DATA<7–0>  
ATA_DATA<7–0> (Odd Byte) put onto PC_DATA<15–8>  
Table 60 describes the PCMCIA Host read and write address examples.
