HOP = Halftone Operation
LOP = Logical Operation
All timings are assuming the BLITTER is the only DMA device using the BUS. If other devices are using the BUS the figures may increase.
All timing figures are given in nops per word of transfer. Ie. a value of 2 would take the equivilent time of 2 nops to transfer 1 word of data.
