The MOVX A,@DPTR and MOVX @DPTR,A instructions are used to access these extended SFRs. [2] The BOICFG1/0 will be copied from UCFG1.5 and UCFG1.3 when power-on reset. [3] CLKCON register reset value comes from UCFG1 and UCFG2. The reset value of CLKCON.2 to CLKCON.0 come from UCFG1.2 to UCFG1.0 and reset value of CLKDBL bit comes from UCFG2.7. Table 7.
