How many gates are there in Z80?
Since there are 8 gates in total – one for each data bit – they can be thought of as another full 8-bit register sitting on the data bus.
How many registers are in the Z80?
The Z80 processor contains 14 general purpose registers which can be used for holding and manipulating data bytes. Each of these registers is 8-bits wide and they are named A, B, C, D, E, H, L, A’, B’, C’, D’, E’, H’, L’.
