Extended SFRs are physically located on-chip but logically located in external data memory address space (XDATA). The MOVX A,@DPTR and MOVX @DPTR,A instructions are
used to access these extended SFRs.
The BOICFG1/0 will be copied from UCFG1.5 and UCFG1.3 when power-on reset.
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.
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.
