OK, this is for MOVX @DPTR. My question #1 was, what about MOVX @Ri.
..... My question #2 was, whether this "reappearance" of Port2 SFR is accompanied by the 2-oscillator strong pullup, or not. If it is @Ri, there is no reappearance of P2. In that case the P2 contents (latch and possible holddowns) is the high address and do not change. The "schematic" of the ports strongly suggest (the XOR) that a strong pullup will occur. Erik |
