AC electrical characteristics assume 50% duty cycle for the oscillator, oscillator frequency ≤ 75MHz, and are not 100% production
tested, but are guaranteed by design.
In PMM mode, the master pulls the line low after the first 15µs for the remainder of the standard speed 1-Wire routine.
This parameter quantifies the wait time for the slave devices to respond to the reset pulse and is dependent on the slave device
timing.
This parameter quantifies the wait time for the case when no presence pulse detected.
The maximum timing figures shown apply only when an exact 1-Wire clock frequency can be achieved from the microcontroller
input clock.
