PARAMETER
fTCK
TCK frequency (at HCLKmax)
fRTCK
RTCK frequency (at TCKmax and HCLKmax)
1 td(TCK -RTCK)
Delay time, TCK to RTCK
2 tsu(TDI/TMS - RTCKr) Setup time, TDI, TMS before RTCK rise (RTCKr)
3 th(RTCKr -TDI/TMS) Hold time, TDI, TMS after RTCKr
4 th(RTCKr -TDO)
Hold time, TDO after RTCKf
5 td(TCKf -TDO)
