other areas in flash ROM on the CPU board are cleared.
(10) If this command is not sent, the storage area in flash ROM on the CPU board
cannot be used.
If "AA" is set for the size of the BASIC file storage area with the BASIC file storage
area being unallocated, the BASIC file storage area remains unallocated.
(11) The storage areas except for the BASIC file storage area are allocated in the
following order of precedence – the TrueType font storage area, and the bit map
writable character storage area.
remaining area is used for the PC save area.
(12) If the sum of the TrueType font storage area and the bit map writable character
storage area, specified by this command, is the size of '896 KB minus the BASIC
file storage area size', the TrueType font storage area and the bit map writable
character storage area are allocated as specified. In this case, however, there is
no PC save area.
(13) If the sum of TrueType font storage area and the bit map writable character
storage area, specified by this command, exceeds the size of '896 KB minus the
BASIC file storage area size', the TrueType font storage area is allocated as
specified with the highest priority. Then, the remaining area is allocated to the bit
map writable character storage area. There is no PC save area.

for either the TrueType font storage area or the bit map writable character storage
area, each area other than the BASIC file storage area is allocated as specified.

area while the BASIC file storage area secures "4" (256KB), the entire storage
areas except the BASIC file storage area are allocated to the TrueType font
storage area. There is no bit map writable character storage area or PC save
area.
