Task File register access specifications 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 register read and write operations are executed under the condition as follows. That area can be accessed by Byte/Word/Odd Byte mode which are defined by PC card standard specifications.
