Anthony Pele – 03/20/2006 What is DSM (Deep Sleep Mode)? DSM refers to many things and then often causes confusions 1.MCU standpoint MCU is stopped SDMA, SDHC etc… are in standy/stop mode 2.DSP standpoint RF is driven into standby mode through WB & MB Deep Sleep Modules DSP is stopped 3.Overall system standpoint MCU/DSP & RF are in Deep Sleep Mode Power Management is driven in standby mode System clock is off Argon core voltage driven to retention level

Anthony Pele – 03/20/2006 USE-CASES CLARIFICATIONs/EXCEPTIONS In Voice call, system never enters « system DSM » state due to sleep/wake-up latency timings (clocks wake-up, power back to high power mode). They are too long compared to RF frames duration. MCU/DSP sides are completely asynchronous. « System DSM » occurs only when everything on the platform is in DSM mode. « System DSM » is also often called « Idle Mode »
