PCMCIA Interface :
The PCMCIA standard, originally created to standardize memory-card to personal-computer
interface, now includes I/O devices. It defines signals, voltage levels, and socket- and card-
cervices that control hardware. The PC Card-ATA Mass Storage Standard combines PC card
interface requirements with the industry-standard ATA specification.
In addition to primary and secondary ATA addressing modes, PCMCIA specifies linear,
independent I/O and linear memory-mapped modes. The PCMCIA-ATA specification goes
beyond the ATA specification’s 16-bit-only data register and 8-bit-only task file register
addressing protocol. It allows all ATA register accesses to be either 8- or 16-bits which allows a
wide variety of system architectures to access PCMCIA-ATA drives.
