Timing improvements

Browse Source 
* Reduce delays from 200 ms to 100 ms, since 200 ms tends to be too long
  overall.
* Increase pulse interval to 30 ms to avoid the chance of stray pulses
  after MCU starts sending info packet.
* Add 30 ms delay after autoreset cycle to avoid glitches on startup
