The CPU View

You can find this view in the Debug activity tag with the Z80 CPU header:

When you hover the mouse over the information items, they display a tooltip with numbers in multiple radixes (whenever that has a meaning).

You can read this information in this panel:

• Z80 registers: All the standard Z80 registers (moving the mouse over the values will display LSB and MSB separately). The WZ is an internal Z80 register, often called MEMPTR.
• LMR: Last value read from memory
• LMW: Last value written to memory
• IRV: Last value read from an I/O port
• IWV: Last value written to an I/O port
• IM: Current interrupt mode
• SNZ: Is the CPU in snoozed mode (Cambridge Z88 uses this CPU mode)
• IFF1: Interrupt flip-flop #1
• IFF2: Interrupt flip-flop #2
• INT: Is the INT signal active?
• HLT: Is the CPU halted?
• CLK: The current clock count since the last machine start
• TSP: T-states elapsed since the last pause. You can use this value to check the number of T-states used between two pauses.
