t
ADS# signal may be tied low if address is stable during read or write cycles.
t
In Isochronous mode, transmitter data is available after the falling edge of the x1 clock and the receiver data is sampled using the
rising edge of the x1 clock. The system designer is should ensure that mark-to-space ratio of the x1 clock is such that the required
set-up and hold timing constraint are met. One way of achieving this is to choose a crystal frequency which is twice the required data
rate and then divide the clock by two using the on-board prescaler. In this case the mark-to-space ratio is 50/50 for the purpose of
set-up and hold calculations.
