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 BOICFG2/1/0 will be copied from UCFG1.5 to UCFG1.3 when power-on reset.
CLKCON register reset value comes from UCFG1. The reset value of CLKCON.2 to CLKCON.0 come from UCFG1.2 to UCFG1.0 and reset value of CLKDBL bit comes
from UCFG1.7.
