Parallel Interface Data Transfer Rate Modification
Ta, Tb, and Tc
Each of these options specifies time intervals (in microseconds) affecting the data
transfer rate for the Parallel Interface. For a Parallel Interface connection that
supports faster data transfers, you can specify smaller values for these fields.

The operation of these settings depends on the settings for the Strobe and Busy
Req parameters, as follows:
 If Busy Req is 0, Ta is the interval from either the beginning of the strobe
signal (if the Strobe setting is Early) or the end of the strobe signal (if the
Strobe setting is Late) to the beginning of the acknowledgment signal. Tb is
the interval of the acknowledgment signal.
 If Busy Req is 1, 2, or 3, Ta is the interval from the beginning of the busy
signal to the end of the busy signal or the beginning of the acknowledgment
signal (whichever comes first).
- If Busy Req is 1, Tb is the interval between the end of the busy signal and
the beginning of the acknowledgment. If Busy Req is 2, Tb is the interval
between the beginning of the acknowledgment and the end of the busy
signal. If Busy Req is 3, Tb is the length of the acknowledgment signal.
- If Busy Req is 1, Tc is the length of the acknowledgment. If Busy Req is 2,
Tb is the interval between the end of the busy signal and the end of the
acknowledgment. If Busy Req is 3, TB is the interval between the end of
the acknowledgment and the end of the busy signal.
Reset Settings
This option restores the factory default settings for the interface (Early Strobe,
Busy Req of 2, 4.625 for Ta, 0.5 for Tb, and 0.5 for Tc).
