DATAMAN 848 MANUAL
Operation 43
This option only applies to chips that are electronically
erasable. It causes DATAMAN-848 to automatically erase
non-blank chips prior to programming.
Blank Check on Erasing Option
This option causes DATAMAN-848 to automatically
perform a blank check on a device after performing an
Erase operation on it. This assures that a chip has been
erased completely.
Device ID Check on Erasing Option
Some chips feature an option that allows the device ID
information to be erased when the chip undergoes an
erase operation. This option must be disabled prior to
erasing the chip; otherwise, DATAMAN-848 will report an
ID mismatch error and stop operation.
Unprotect on Erasing Option
Some Flash chips have a software protection feature
which, when enabled, prohibits erasure of the chip's
memory. The unprotect option on these chips must be
enabled before trying to erase these chips.
Standard Mode on Mass Production
In this mode, the 8 sockets of the DATAMAN-848 work as
a group. Insertion testing and programming is performed
on all 8 sockets simultaneously.
Concurrent Mode on Mass Production
In this mode, the 8 sockets of the DATAMAN-848 are
divided into two groups. Sockets 0 to 3 comprise group 1
and sockets 4 to 7 comprise group 2. The user can extract
programmed chips and insert new chips in group 2 while
programming the chips in group 1. Once programming is
completed, the chips in group 2 are programmed while the
chips in group 1 are removed and replaced with new chips.
The process is then repeated.
