Function
Must be set to ‘1’ if GA is to start memory transfer after executing this
GA-instruction. Otherwise this bit must be set to ‘0’.
Quadruple Height during Transfer
‘0’: Normal height is selected.
‘1’ The memory transfer is stretched in vertical direction on the output
side.
Underline on/off
0: Underline is switched off.
1: The last line (independent from ‘TDH’) in the destination area is
filled with a constant CLUT1 input (vector 0 of CLUT1) instead of
the source bitmap input.
Clipping on/off
00: Clipping is switched off.
01: Reserved.
10: Clipping is switched on. Pixels within the clipping area will be
affected.
11: Clipping is switched on. Pixels outside the clipping area will be
affected.
Transparency Mode for Transfer
‘0’: The complete area defined by instruction SDR and TDR is written
to the destination.
‘1’: Only these (4:4:4:2) pixels are written to the destination area, for
which Bit TR1 = ‘0’.
Note: This bit is only relevant for 16-bit (4:4:4:2) RGB output formats
