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. [4] On power-on reset and watchdog reset, the PGAxTRIM8X16X and PGAxTRIM2X4X registers are initialized with a factory preprogrammed value. Other resets will not cause initialization. Table 7.
