Control and Status Registers

The Z86D99/Z86L99 family has 4 I/O port registers, 33 status and control regis-

ters, and 233 general-purpose RAM registers. The I/O port and control registers

are included in the general-purpose register memory to allow any Z8 instruction to

process I/O or control information directly, thus eliminating the requirement for

special I/O or control instructions. The Z8 instruction set permits direct access to

any of these 37 registers. In addition, each of the 233 general-purpose registers

can also function as an accumulator, an address pointer, or an index register.

Registers identified as “Reserved” do not exist or have not been implemented in

this design.
