Module Specific Syntax 3-22 EADS North America Defense

specify that bit 3 will go high in vector 1, bit 1 will go high and bit 3

will go low in vector 2, and bits 5 and 7 will go high in vector 3.

The second SETUP statement will leave the buffer intact and will

specify that in vector 4, bits 1 and 7 will go low. Once the test is

armed, port 0 would be actively driving a binary 00001000 after the

first clock, a 00000010 after the second, a 10100010 after the third

and a 00100000 after the last clock.

WRITE command

Syntax: Byte: WR[ITE] <address>.<ports>[,Y][,<byte>,...,

<byte>]

Word: WR[ITE] <address>.<ports>[,W][,<word>,...,

<word>]

Bit: WR[ITE] <address>.<ports>[,X][,<bits>;.....;<bits>]

<address>::= Module address of the 1260-14 (1-12)

<ports>::= One or more consecutive ports to write to. A single

port is specified as a decimal number from 0 to 11. A group of

ports is specified as two decimal numbers from 0 to 11 separated

by a hyphen, (-), with the least significant port to the right and the

most significant port to the left. For example, the command WR

1.3-5,Y,0,1,2 would write a 0 in port 3, a one in port 4 and a 2 in

port 5. Data may be specified in decimal, hexadecimal or binary.

<byte>::= An 8-bit value specified as either decimal format (0-

255), hexadecimal format (H0-HFF) or binary format (B0-

B11111111). Note that the "H" is required in front of hex values

and the "B" is required in front of binary values.

<word>::= A 16-bit value specified in either decimal format (0-

65535), hexadecimal format (H0-HFFFF) or binary format (B0-

B1111111111111111). Note that the "H" is required in front of hex

values and the "B" is required in front of binary values.

<bits>::= Specifies up to eight single bit transitions in the form

Lx|Hx,...Lx|Hx where x specifies which bit number to write high

(Hx) or low (Lx), and x may take the values from 0-7. For example,

WR 1.1-2,X,L1,L3;H0,H1 would cause bits 1 and 3 to go low in port

1 and bits 0 and 1 to go high in port 2.

Description: This command performs an asynchronous write to a

single port or a group of consecutive ports. No handshaking is

required for this operation. The command is primarily used to write

to asynchronous ports, but may be used to preset synchronous

ports to a known value before starting synchronous operations.
