Timing µsec-bus
Notes for the timing:
Timing definitions are starting or ending at a voltage level of 1V (Low Level) resp. 2V (High Level).
During SSY = high the clock at FCL may be interrupted, i.e. there is no need for a clock during SSY = high.
The clock signal may remain on high or low statically during SSY = high.
A rising edge at SSY and a falling edge at FCL must not occur simultaneously!
On the rising edge of SSY the 16 bits clocked in TLE6244X by the last 16 falling edges at FCL are latched.
