22. Register 26hex
Data7: Unused (Must be set to 0.)
Data6: R/W
Function: Bit map data area read/write mode setting
Operation: Sets the bit map data to read or write mode.
R/W = 0: Bit map data area set to write mode
R/W = 1: Bit map data area set to read mode
Data5: Unused (Must be set to 0.)
Data4: STRP/ENDP
Function: Bit map data setup area start or stop coordinate selection
Operation: Loads the coordinates set up by registers 24hex, 25hex, and the Data0 bit (BMAX8) of this register
into the bit map data setup area start or stop address.
STRP/ENDP = 0: Sets the start coordinates.
STRP/ENDP = 1: Sets the stop coordinates.
Data3: FILLCOLR
Function: Bit map area color palette color fill operation setup
Operation: Fills the bit map area specified with STRP/ENDP with the color palette color specified by the 4 bits
Data3 to Data0 (BMD3 to BMD0) in register A7hex.
The execution of the fill operation starts after the color palette is set with register A7hex.
FILLCOLR = 0: Fill operation not set up.
FILLCOLR = 1: Sets up a fill operation.
Data2: BMAI
Function: Automatic bit map address increment during bit map data write setting
Operation: Specifies whether or not the bit map address is automatically incremented during bit map data write
operations.
If automatic incrementing is not specified, the application must specify the address in registers
24hex, 25hex, and 26hex after every data transfer.
BMAI = 0: The address is not automatically incremented.
BMAI = 1: The address is automatically incremented.
Data1: BMDF
Function: Bit map data transfer item count setting
Operation: Specifies whether data is transferred in dot units or in two-dot units during bit map data transfers.
This is a setting that determines whether only the lower 4 bits or all 8 bits are transferred in register
A7hex data transfers.
BMDF = 0: Takes only the lower 4 bits as data.
BMDF = 1: Takes all 8 bits as data.
Here, the lower 4 bits of data are taken as the first data item, and the upper 4 bits are
taken as the next data item.
Note: BMDF must be set to 0 when BMAI is set to 0, i.e. when automatic address incrementing is not used.
