#159450 - Your T7 Responding to: ???'s previous message |
Your T7 parameter is a MAXIMUM time from rise of the clock till the slave target has shifted out his data on the SDO line. After the 20 nsec MAX the SDO will stay valid till the next clock rising edge.
So you have all the time in the clock cycle to read the data. It is common to strobe such data off the SDO line into the master on the subsequent fall time of the clock line. If bit banging gather the SDO data in just after the bit handling routine sends the clock to a low level. Michael Karas |
