3.1.3 Vector Engine Functions
DM482e allows user to generate or analyze user-defined patterns for each pin. Patterns are
defined in a vector file (*.vec). Each vector file consists of one vector set only. Refer to
specifications for the maximum number of supported vector set and timing set per DM482e.
If a pin is configured as an input-only or output-only pin, the data rate can achieve the
maximum performance of DM482e. On the other hand, if a pin is configured as bi-directional
pin, its maximum data rate is lower. Refer to specifications for details.
Figures below show the pattern format for dedicated pins and bi-directional pins.
Figure 8: Vector Format for Dedicated Input-only or Output-only Pins
User defines input and output
pins. User has to define every pin.
Undefined pins will return error. If
user instantiates pin-group 0 or 1,
the defined pin range is from 0 to
5.
User defines the sequence for the
vector. In this example, the first
column (highlighted in green)
represents Pin 11 and sixth column
(highlighted in yellow) represents
Pin 6 and etc.
tx refers to trigger output pins.
Definition of Its pin direction is not
required.
This specifies the timing set
number to be used for this vector
set. The value of each timing set
can only be defined using
DM482e_DPINPeriod function.
There are six data formats:
'0' : Drive Low (output only)
'1' : Drive high (output only)
'Z' : Tristate (output only)
'L' : Compare Low (input only)
'H' : Compare High (input only)
'X' : Don't Compare (input only)
