Hello,
This is regarding the IDE signal measurements. For the write we need to trigger
the data at device (eg:hdd) with reference to strobe (IORDY), in the ata spec
it was shown that setup and hold time wrt to strobe falling and rising edge.
the IORDY signal is active high but in the spec the tds and tdh are shown wrt
both the edges of strobe (iordy). do we need to take it this way for both?
is it same measurement for write operation also but with DIOR as storbe?
Regards
Santhosh
