#121742 - and so what Responding to: ???'s previous message |
... the bad news is, that you cannot use P2 for high address of "internal-external" memory when using movx @r0 etc...
most derivatives with 'internal xram' do have a 'high address' register. example the SILabs f12/f13x have the EMI0CN SFR thatv specify the uppre address for movx @Ri Erik |
