Functional Description

Notes When the initial bus state is idle, tB1 reflects the number of CLK periods from the rising edge of the CLK that drives TS_low, to the rising edge of the CLK that samples the first TA_low.

When the bus is busy and TS_ is being asserted as soon as possible after Hawk asserts AACK_ the back-to-back condition occurs. When back-to-back cycles occur, tB1 reflects the number of CLK periods from the rising edge of the CLK that samples the last TA_ low of a data tenure to the rising edge of the CLK that samples the first TA_ low of the next data tenure.

The tB2 function reflects the number of CLK periods from the rising edge of the CLK that samples the first TA_ low in a burst data tenure to the rising edge of the CLK that samples the second TA_ low in that data tenure.

The tB3 function reflects the number of CLK periods from the rising edge of the CLK that samples the second TA_ low in a burst data tenure to the rising edge of the CLK that samples the third TA_ low in that data tenure.

The tB4 function reflects the number of CLK periods from the rising edge of the CLK that samples the third TA_ low in a burst data tenure to the rising edge of the CLK that samples the last TA_ low in that data tenure.
