18.15 Instruction Prefixes
18.16 Block Move Instructions
If any of the block move instructions are prefixed by an I/O prefix, the destination will be
in the specified I/O space. Add 1 clock for each iteration for the prefix if the prefix is IOI
(internal I/O). If the prefix is IOE, add 2 clocks plus the number of I/O wait states enabled.
The V flag is set when BC transitions from 1 to 0. If the V flag is not set another step is
performed for the repeating versions of the instructions. Interrupts can occur between dif-
ferent repeats, but not within an iteration equivalent to LDD or LDI. Return from the inter-
rupt is to the first byte of the instruction which is the I/O prefix byte if there is one.
