AND1 is an SPC700 instruction that performs a logical AND between a memory bit and the carry flag, then stores the conjunction in the carry flag. The low 13 bits of the operand specify an absolute address. The high 3 bits of the operand specify which bit at that absolute address.

The bit reversal operator may be prefixed to the memory bit address, in which case opcode 6A is assembled.
