#175238 - Read about external Gate for Timer Responding to: ???'s previous message |
On falling edge prepare Timer - load 0xfff into Timer, which Gate is connected to monitored signal too.
When signal goes high Timer will increase from 0xffff to 0x0000 - and generates interrupt - if enabled. Or i'm wrong and this needs inverter too?! regards |
