Watchdog
MAD4 must reset the CCONT watchdog regularly. CCONT watchdog time can be set
through SIO between 0 and 63 seconds at 1 second steps. After power–up the default
value is 32 seconds. If the watchdog expires, CCONT will cut off all supply voltages. After
total cut–off the phone can be re–started through any normal power–up procedure.
CCONTs watchdog functionality may be temporarily disabled by holding CCONTs
PWRONX/WDDISX pin at logic low.
Power Up
There are four ways to power on the phone.
1. Power Up by Power Button
2. Power Up With Charger Connected
3. Power Up by IBI
