2, the mobile phone start that powers on, in program initialization work, timing pulse generator is just started working, and generates accurate commutator pulse P;
3, commutator pulse P is sent to the step-by-step counting part of base band, and this segment count begins constantly the commutator pulse P that brings to be counted, and the numerical value A of generation constantly is sent to the clock calculation part;
4, the clock calculation in the base band partly continue to receive numerical value A, and calculates generation time correction TC according to the cycle of commutator pulse.Time correction TC and initial time T0 addition produce new time T R, promptly so-called real-time time.
5, this real-time time TR sends into LCD (LCDs) part in the man-machine interaction part, shows.Usually, show that time T R and current time TB have very big-difference.
6, the user tells master control part to baseband portion current time T B via man-machine interaction part (such as keyboard), and requires the mobile phone correction time.
7, master control part revision program start-up time all gives zero clearing to pulse segment count and clock calculation part, returns to initial condition;
8, master control part is divided the current time TB that receives user's input, and TB is sent to the clock calculation part; Simultaneously, step-by-step counting part also again paired pulses P count, repeat above-mentioned 3 work;
