ADE5166/ADE5169/ADE5566/ADE5569
POWER MANAGEMENT
The ADE5166/ADE5169/ADE5566/ADE5569 have elaborate
power management circuitry that manages the regular power
supply to battery switchover and power supply failures.
Table 16. Power Management SFRs
Data Sheet
The power management functionalities can be accessed directly
through the 8052 power management SFRs (see Table 16).

Writing to the Interrupt Pins Configuration SFR (INTPR, Address 0xFF)
To protect the RTC from runaway code, a key must be written to the key SFR (KYREG, Address 0xC1) to obtain write access to the
INTPR SFR. The KYREG SFR (see Table 126) should be set to 0xEA to unlock the INTPR SFR and reset to 0 after a timekeeping register is
written to. The RTC registers can be written using the following 8052 assembly code:

KYREG, #0EAh
INTPR, #080h
