Data I/O 298 Manual page 132

Upon successfui programming of a part the
piOgrammer outputs a count of the number
of programming operations completed, To
reset this count see the "CD" command.
Pressing the RETURN key repeats the
Program operation.
VERIFY Command
Operation:
Code:
Syntax:
VERIFY (Device vs. RAM)
VF
(>)
[V] [F] [Begin RAM Address] [/]
[Number of Bytes] [/] [Begin Device Address]
[CR]
Explanation: This command compares data in a device
with data in RAM. If address limits are
specified, verification occurs only within the
specified number of bytes, starting at the
specified RAM and device addresses. If
address limits are not specified the entire
device data is verified against the RAM data.
For 4-bit devices, device data will be verified
against the low-order nibble of RAM. After a
successful verification, the programmer
returns a sumcheck for the data verified and
displays "VERIFY OK" and a prompt
character.
If the device data fails to verify against the
RAM data the following message is displayed
on the terminal CRT screen: "PASS 1
VERIFY ERRORS
=
NN," where NN is a
number denoting the quantity of errors. There
could also be a "PASS 2 VERIFY ERRORS
= NN" if errors were only detected on the
second of the two verify passes.
Also the address, RAM data and device data
for each mis-verify location is displayed on
the terminal's CRT screen. At the last mis-
verify location, the sumcheck for the RAM
data is displayed along with the message
"VERIFY ERROR."
B.8.4 iiO COMMANDS
The following are I/ 0 Commands:
ODD PARITY Command
Operation:
ODD PARITY
Code: OP
Syntax:
(>)
[0] [P] [CR]
Explanation: The programmer sets odd parity for output
data and inspects incoming data for odd
parity. Default Value-programmer's parity-
switch setting.
EVEN PARITY Command
Operation: EVEN PARITY
Code: EP
Syntax:
(> )
[E] [P] [CR]
Explanation: The programmer sets even parity for output
data and inspects incoming data for even
parity. Default Value- programmer's parity-
switch setting.
NO PARITY Command
Operation:
Code:
NO PARITY
NP
Syntax:
(>)
[N] [P] [CR]
Explanation: This command instructs the programmer not
to check input data for parity, and not to set
parity for output data. Default Value-
programmer's parity-switch setting.
DEFAULT PARITY Command
Operation: DEFAULT PARITY
Code: DP
Syntax:
(>)
[D] [P] [CR]
Explanation: This command returns the programmer to the
default parity value, which is the
programmer's parity-switch setting.
