Disable BOD1 to slow down the chip power consumption.
1: Enable BOD1 to monitor VDD power dropped.
Bit 1: BO0RE, BOD0 Reset Enabled.
0: Disable BOD0 to trigger a system reset when BOF0 is set.
1: Enable BOD0 to trigger a system reset when BOF0 is set (VDD meets 1.7V).
Bit 0: Reserved. Software must write “1” on this bit when PCON2 is written.

Bit 7: Reserved. Software must write “0” on this bit when SPCON is written. Bit 6: P6CTL. P6 SFR access
Control.
If P6CTL is set, it will disable the P6 SFR modified in Page 0~F. P6 in Page 0~F only keeps the SFR read
function. But software always owns the modification capability in SFR Page P.
Bit 5: P4CTL. P4 SFR access Control.
If P4CTL is set, it will disable the P4 SFR modified in Page 0~F. P4 in Page 0~F only keeps the SFR read
function. But software always owns the modification capability in SFR Page P.
Bit 4: WRCTL. WDTCR SFR access Control.
If WRCTL is set, it will disable the WDTCR SFR modified in Page 0~F. WDTCR in Page 0~F only keeps
the SFR read function. But software always owns the modification capability in SFR Page P.
Bit 2: CKCTL0. CKCON0 SFR access Control.
If CKCTL0 is set, it will disable the CKCON0 SFR modified in Page 0~F. CKCON0 in Page 0~F only
keeps the SFR read function. But software always owns the modification capability in SFR Page P.
Bit 1: PWCTL1. PCON1 SFR access Control.
If PWCTL1 is set, it will disable the PCON1 SFR modified in Page 0~F. PCON1 in Page 0~F only keeps
the SFR read function. But software always owns the modification capability in SFR Page P.
Bit 0: PWCTL0. PCON0 SFR access Control.
If PWCTL0 is set, it will disable the PCON0 SFR modified in Page 0~F. PCON0 in Page 0~F only keeps
the SFR read function. But software always owns the modification capability in SFR Page P.
