I have tried to run RTCC from SOSC and output RTC clock on one of MCU (PIC24FJ128GA310) pins and then wire it back to some other pin which was later used as TxCK external clock (TxCK External Clock Input).

Can anybody post a piece of code how to setup the timers 2/3/4/5 operate in sleep mode from SOSC? The same about block diagrams - most of them has 'SYNC' component in the path (I suppose sync with system clock)? How can it work - as sync is impossible in sleep mode, due to stopped system clock! I feel like I miss something. The datasheets are very confusing, they say - 'Timer Operation During Idle and Sleep modes', then 'All 16-BitOperating modes (except Asynchronous Countermode)'?!.

Timer2/3/4/5 in sleep mode on PIC24 devicesĭue to certain power related limitations of my application I need more than one asynchronous timer (or timer running in sleep mode from SOSC).Īs per PIC24 datasheets the TIMER2/3 AND TIMER4/5 support operation in sleep mode.
