One of my customers is designing ADUC7061 software for their new system.
He need to minimize power consumption of the board with ADUC7061, his software will controls the Power Saving Mode listed in the Data Sheet page 36.
Initial state will be Active by setting 0x78 into POWCON0 register.
He is testing the behavior by writing in main loop such as, POWKEY1=0x1, then POWCON0=0x70 (CD=0, Pause), then POWKEY2=0xF4. By adding this process in the main loop, however, no change on power consumption and operation from Active state, it seemed no change.
His question is how to set the registers in order to reduce power consumption from Active mode.
Thank you for your help.
