6.3.18 STORAGE AREA ALLOCATE COMMAND [ESC] XF
• For the firmware before V5.0
Function Allocates the storage area in flash ROM on the CPU board.
Format [ESC] XF; aa, bb, cc [LF] [NUL]
Term aa: Size of the TrueType font storage area
00 to 14 (0 KB to 896 KB) (in units of 64 KB)
bb: Size of bit map writable character storage area
00 to 14 (0 KB to 896 KB) (in units of 64 KB)
cc: Size of BASIC file storage area
00 to 14 (0 KB to 896 KB) (in units of 64 KB)
AA: The current BASIC file storage area and contents are retained.
Explanation (1) The storage area in flash ROM has a total capacity of 896 KB.
In case that the size of BASIC file storage area is set in a range of “00” to “14”:
(2) When this command is received, the entire area in flash ROM on the CPU board is
cleared.
(3) If this command is not sent, the storage area in flash ROM on the CPU board
cannot be used.
(4) The storage areas are allocated in the following order of precedence – the
TrueType font storage area, the bit map writable character storage area, and the
BASIC file storage area. After these storage areas are allocated, the remaining
area is used for the PC save area.
(5) If the sum of the TrueType font storage area, the bit map writable character
storage area, and the BASIC file storage area, specified by this command, is 896
KB, the TrueType font storage area, the bit map writable character storage area,
and the BASIC file storage area are allocated as specified, respectively. In this
case, however, there is no PC save area.
(6) If the sum of TrueType font storage area, the bit map writable character storage
area, and the BASIC file storage area, specified by this command, exceeds 896
KB, 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. If there is still remaining area after the TrueType font storage area
and the bit map writable character storage area are allocated, it is used for the
BASIC file storage area. There is no PC save area.
(7) When “00” (0 KB) is specified for each of the TrueType font storage area, the bit
map writable character storage area, and the BASIC file storage area, the storage
area is not allocated.
(8) When “14” (896 KB) is specified for any of the TrueType font storage area, the bit
map writable character storage area, and the BASIC file storage area, the entire
storage areas are occupied by that area. For example, if “14” is specified for the
TrueType Font storage area, the entire storage areas are used for the TrueType
Font storage area. The bit map writable character storage area, the BASIC file
storage area, and the PC save area cannot be allocated.
