It is necessary to compensate the effect of temperature on the phone output power. To monitor this environment change, the temperature measurement is done by using a NTC resistor. A factor table is used for temperature compensation. The table contains common values for all power levels and operating modes. The table values are defined without factory measurements. The temperature is measured and right compensation value is added to the TXC-value. The requirement for compensation update is for...

Both MAD and CCONT include a watchdog, and both use the 32 kHz sleep clock. The watchdog in MAD is the primary one, and this is called SW-watchdog. MCU has to update it regularly. If it is not updated, logic inside MAD gives reset to mAd. After the reset, MCU can read an internal status bit to see the reason for reset, whether it was from MAD or CCONT. The SW-watchdog delay can be set between 0 and 63 seconds at 250 millisecond steps and after power-up the default value is the max. time. MAD...
