EADS North America Defense Module Specific Syntax 3-21

wide operations are specified on even-numbered ports only, and

place the least significant 8 bits in the even port and the most

significant 8 bits in the following odd-numbered port. Word sized

operations may not be mixed with bit or byte operations in either

the even or odd port. If either the even or the odd port is redefined

as a byte-wide or a bit-wide port, both ports will have their buffers

cleared and the matching odd or even companion port will be

disabled in future synchronous operations until redefined.

Example 2:

Assume that ports 0-3 are synchronous ports, ports 2 and 3 were

previously defined as synchronous word-wide write ports, and the

user sends the following commands:

SETUP 1.WR 0,W,H5F01,H6F02,H7F03

SETUP 1.WR 2,Y,16,8,4,2,1

The first command would clear the buffers for ports 0 and 1, and

would cause the module to perform a word-wide write of three

vectors to ports 0 and 1 during the next synchronous test, finishing

the test with the value of hex 03 in port 0 and hex 7F in port 1. The

second command would clear the buffers for ports 2 and 3 and

would cause a byte-wide write of five vectors to port 2 during the

next synchronous test, finishing the test with a value of 1 in port 2.

Port 3 would be disabled from participating in subsequent tests

until redefined.

An "X" specifies a bit-wide write to a port. Any of the 8 bits from 0-

7 may be set to 0 (Low) or 1 (High) by using the form Lx or Hx,

where x is the bit to modify. Multiple bits may be modified by

separating the bit transitions with commas. Multiple vectors may

be set up by separating the changes for each vector with

semicolons. Bits that are not modified remain in their previous

states. If the port was previously defined using a word width, the

data associated with the companion port will be cleared, and the

port will be disabled in future synchronous operations until

redefined.

Example 3:

Assume the user sends the following two statements to the module

and the current value of port 0 is a binary 00000000:

SETUP 1.WR 0,X,H3;H1,L3;H5,H7

SETUP 1.WR 0,L1,L7

The first SETUP statement will first clear the buffer for port 0, then
