Enhanced single Cell Li-Battery and Power System Management IC

issuing a timer interrupt. Write 1 in register REG8AH [7] to clear the flag and re-start timing. Clearing

interrupt flag will not re-start counting. The minimum step size for the timer is 1 minute, and the timing

range 1 ~ 127 Minutes.

9.10 Decryption

AXP209 Contains a decryption module. The Host writes data to REG300-REG30F to be decrypted,

and then writes 1 to the register REGB8H [1] to start decryption. After the decryption is complete,

status bit REGB8 [0] is set to 1. Then the Host can read back the decrypted data from REG31x. Starts

again automatically when the decryption AXP209 status bits are clared.
