CC is a conditional CALL -- the two-byte address specified in the first operand will be called only if the carry bit is set. The conditions for the CALL (C...), JMP (J...), and RET (R...) are: NZ not zero Z zero NC not carry C carry PO parity odd OE parity even (is this a typo? I suspect it's really PE) P plus M minus The XTHL exchanges the contents of the H-L register with the two-byte space located at where the stack point (SP) is pointing. If you need any help with looking up other ones, or would like to know specific conditions, I'd be glad to help.
