Copper moves happen 2 cycles after state READ2 is reached. + It can't happen immediately when we reach READ2, because the + data needs time to get back from the bus. An additional 2 + cycles are needed for non-Agnus registers, to take into account + the delay for moving data from chip to chip. + 2. As stated in the HRM, a WAIT really does need an extra cycle + to wake up. This is implemented by _not_ falling through from + a successful wait to READ1, but by starting the next cycle. + (Note: the extra cycle for the WAIT apparently really needs a + free cycle; i.e. contention with the bitplane fetch can slow + it down). + 3. Apparently, to compensate for the extra wake up cycle, a WAIT + will use the _incremented_ horizontal position, so the WAIT + cycle normally finishes two clocks earlier than the position + it was waiting for. The extra cycle then takes us to the + position that was waited for. + If the earlier cycle is busy with a bitplane, things change a bit. + E.g., waiting for position 0x50 in a 6 plane display: In cycle + 0x4e, we fetch BPL5, so the wait wakes up in 0x50, the extra cycle + takes us to 0x54 (since 0x52 is busy), then we have READ1/READ2, + and the next register write is at 0x5c. + 4. The last cycle in a line is not usable for the copper. + 5. A 4 cycle delay also applies to the WAIT instruction. This means + that the second of two back-to-back WAITs (or a WAIT whose + condition is immediately true) takes 8 cycles. + 6. This also applies to a SKIP instruction. The copper does not + fetch the next instruction while waiting for the second word of + a WAIT or a SKIP to arrive. + 7. A SKIP also seems to need an unexplained additional two cycles + after its second word arrives; this is _not_ a memory cycle (I + think, the documentation is pretty clear on this). + 8.
