![]() ![]() So I defined an interface to represent everything I needed out of a 16 bit register. So from a coding point of view, I decided to treat these 16 bit registers as separate things. Sharp, Z80, Z80A, LH0080A, 4, MHz, DIP40, CPU, 4MHz, processor, Sharp, MZ-700, classiccomputershop,, kopen, koop, verkoop, buy. So when loading a value into the BC register, the high order byte will be stored in the B register and the low order byte will be stored in the low order byte. ![]() In addition to all features, found in Z80, the Z84C01 adds on-chip clock generator, and allows external hardware to control how the processor operates when HALT instruction is executed. The first register contains the high order byte and the second contains the low order byte. Z84C01 microprocessor is object-code compatible with Z80 CPU, but is not pin-compatible with it. As to if that can generate the symptoms mentioned or damage the device, Im not sure. It contains the Stack Pointer which contains the address of the top of the stack (we will get into this more in a future post).Īnd it contains the Program Counter which is the address of the currently executing instruction.īut it also contains faux 16 bit registers made up of the 8 bit registers.īC, DE and HL can each be treated as a 16 bit register despite actually being two 8 bit registers. 3 The datasheet lists a minimum clock cycle time so manually generating the clock with a mechanical switch is unlikely to work. It contains the IX and IY registers which are used for indexing into tables. Z80 CPU Central Process Unit, Z8400 Datasheet, Z8400 circuit, Z8400 data sheet : STMICROELECTRONICS, alldatasheet, Datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs and other semiconductors. In fact, it contains 7 16 bit registers that are available at any one time. ![]() It it still being used in new pieces of hardware or is it totally obsolete z80 Share. Most of our work so far has been using 8 bit registers but the Z80 CPU also contains 16 bit registers. I have seen that some people are asking questions about assembly programming using the Z80 CPU. ![]()
