4.7.4.36
Code:
Definable area: aE = 00h – 04h
Function:
FROM bit image capacity is 32,768 bytes + Extension area 262,144 bytes.
Data is defined or changed from the specified Bit image data definition address for the number of
bytes specified by Bit image data length.
Bit images defined in FROM can be displayed using 4.7.4.37 Downloaded bit image display
command.
The least significant bit for both Bit image data definition address and Bit image data length is
ignored – these are processed as even values.
If Bit image data definition address or Bit image data length is outside the definable area, the
command is cancelled at that point, and the remaining data is treated as standard data.
This command is only valid in User setup mode.
BUSY signal is output by the display module during processing of this command. The host should
not transmit any data during this time.
aE = 00h:
Total definable area is 000000h to 007FFFh (32,768 bytes). Bit image definition is performed in units
of 2 bytes.
aE = 01h – 04h:
Total definable area is 010000h to 04FFFFh (262,144 bytes). Bit image definition is performed in
units of 65536 bytes (64KB). For example, if 10KB of bit image data is defined, the remaining 54KB
data is set to FFh.
Bit image data definition address cannot be specified in such a way that the definition data would
overflow into the area of the next extension byte (for example, 01xxxxh – 02xxxxh). The command is
cancelled if this situation is detected, and the remaining data is treated as standard data.
Defined contents are not guaranteed if an error occurs.
