MOVEP Instruction
The instruction MOVEP (MOVE Peripheral) transfers a word or longword in a data register to or from every second memory address. The MSB in the data register transfers to or from the address x(An), - the only address method - the next byte to or from x+2(An) and so on. If the first address was odd all MOVEP transfers will use the lowest byte in the 68000:s databus. Even addresses use the highest byte. This instruction is mainly used when you use 8 bit data buses connected with the 16 bit databus in the 68k. Since this is never done on the TI-92 this instruction won't be used that way.
