This sequence of commands is used to specify the number of flash sectors to be used for different applications. The begin
and end sequence commands must be sent. All areas do not need to have flash sectors specified.
The command to request the number of user sectors is optional.
If more sectors are specified than are available the command sequence is ignored and the printer returns NACK.
If the sectors are available, and different from current parameters, all sectors are erased and the printer returns ACK.
If the sectors specified are the same as current parameters, nothing is erased and the printer returns ACK.
1D 22 80 00 request number of user sectors available, printer returns nL nH
1D 22 80 30 begin expanded flash memory allocation sequence
1D 22 80 31 nL nH n sectors to logo/font area
1D 22 80 32 nL nH n sectors to user data storage area
1D 22 80 33 nL nH n sectors to permanent font area
1D 22 80 34 nL nH n sectors to electronic journal area
1D 22 80 40 end expanded flash memory allocation sequence
n = 0xFFFF means allocate all remaining sectors to this area; only one area can specify this parameter value.
