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>
