Flash Allocation - NCR 7158 Owner's Manual

Flash Allocation

ASCII:
Hexadecimal:
Decimal:
Default Value of n1: 1
Default Value of n2: 1
n1 is the number of 64k sectors used for logos and user-defined
characters.
n2 is the number of 64k sectors used for user data storage.
This command sets the allocation of Flash sectors between user data
storage and logos/user-defined characters. This allocation is saved in
the EEPROM of the printer and is therefore saved across power cycles.
n1 + n2 <= 2 (512K)
n1 + n2 <= 10 (1M)
n1 + n2 <= 18 (2M)
The 7158 has been configured at the factory with 512K, 1M or 2M of
Flash memory. If n1 + n2 is greater than the maximum number of
sectors available, the command is ignored. Reissuing this command
with different parameters will erase all sectors.
Exception:
This is command is available only in A758 Native Mode
