Notes: 1. These signals are required only for 16 bit access and not required when installed in 8 bit systems. Devices should allow
for 3-state signals not to consume current.
2. Should be grounded by the host.
3. Should be tied to VCC by the host.

There are two cases of Task File register mapping, one is mapped I/O address area, the other is mapped
Memory address area. Each case of Task File registers read and write operations is executed under the
condition as follows. That area can be accessed by Byte/World/Odd Byte modes, which are defined by PC card
standard specifications.
