Note 7

This spec is for 1st bit only Remaining bits are spec’d by transmitter TVTC spec

Note 8

Receiver specs TVRS and TVRH are required along with TLFS for receiver operation using serial decoder

Note 9

This spec is for 1st bit only and is measured from the later of either FS or HCK1 rising edge Remaining bits are spec’d from HCK1 rising edges by

transmitter TVTC spec
