User Manual 1260-14C
Module Specific Syntax 3-3
Synchronous Mode
Handshaking
The module has a two-line handshake available for use in the
synchronous mode. The first is the BUSY line, which is set by the
1260-14C when it is busy processing, and the second is the
CLKIN line which the user toggles to clock the next synchronous
operation. The user specifies the polarity of the BUSY line and the
active edge of the CLKIN line by using the appropriate SETUP
command. (Refer to Figure 3-1 for timing diagrams of the input
and output handshaking modes available.) Both the BUSY and
CLKIN lines are valid only when a synchronous operation is
defined and armed.
NOTE
Both the BUSY and the CLKIN lines are valid only
when synchronous operations are defined and
armed. Changes on the CLKIN line are ignored by the
1260-14C when the card is not armed. Spurious
outputs on the BUSY line should also be ignored
unless the unit is armed.
