CPU Registers
Figure 1.
The Z80 CPU contains 208 bits of R/W memory that are available to the
programmer. Figure 2 illustrates how this memory is configured to eighteen
8-bit registers and four 16-bit registers. All Z80 registers are implemented
using static RAM. The registers include two sets of six general-purpose
registers that may be used individually as 8-bit registers or in pairs as 16-bit
registers. There are also two sets of accumulator and flag registers and six
special-purpose registers.
