edisondeng	767aa14086	fix(timer): compensate Timer0_GetTimestamp for pending TF0 overflow ... TH0/TL0 torn-read protection didn't cover the case where the hardware counter already wrapped but Timer0_Isr hasn't run yet to bump timer0_ovf_count, making the timestamp appear to jump backward by one overflow period (~32.768ms). Read TF0 under a brief EA guard and treat a pending-but-unserviced overflow as ovf+1 without clearing it.	2026-07-31 15:52:50 +08:00
