MOV1 is an SPC700 command that moves a memory bit to or from the carry flag. The low 13 bits of the operand byte specify an absolute address. The high 3 bits of the operand byte specify which bit at that absolute address.
The operands are stored in the instruction stream in the opposite order they appear in the assembler source. In the assembler source, the operand on the right is the source and the operand on the left is the destination.
