[1] 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.

[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.
