DRAW_ERR3 is reset by writing 1.
The GE does not stop command execution even if this error has occurred.
D2
DRAW_ERR2: Color Depth Over Error Flag Bit
Indicates whether a color depth over error has occurred in the drawing stage or not.
1 (R):
Error has occurred
0 (R):
No error has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
DRAW_ERR2 is set to 1 if the specified drawing color or a pixel color in the image data is out of the
effective range for the bpp mode set in the GE.
When DRAW_ERR2 is set to 1, a drawing error interrupt request is output to the ITC if GE_ERR_IE0
has been set to 1 (interrupt enabled). An interrupt is generated if the ITC and C33 PE Core interrupt
conditions are satisfied.
DRAW_ERR2 is reset by writing 1.
The GE does not stop command execution even if this error has occurred.
D1
DRAW_ERR1: Clipping Area Over Error Flag Bit
Indicates whether a clipping area over error has occurred in the drawing stage or not.
1 (R):
Error has occurred
0 (R):
No error has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
DRAW_ERR1 is set to 1 if the whole of an object/image drawn by a command with clipping area en-
abled is located outside the clipping area. If a part of an object/image is beyond the clipping area, the
drawing within the clipping area is performed without an error.
When DRAW_ERR1 is set to 1, a drawing error interrupt request is output to the ITC if GE_ERR_IE0
has been set to 1 (interrupt enabled). An interrupt is generated if the ITC and C33 PE Core interrupt
conditions are satisfied.
DRAW_ERR1 is reset by writing 1.
The GE does not stop command execution even if this error has occurred.
D0
DRAW_ERR0: Work Area Over Error Flag Bit
Indicates whether a work area over error has occurred in the drawing stage or not.
1 (R):
Error has occurred
0 (R):
No error has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
DRAW_ERR0 is set to 1 if the whole of an object/image drawn by a command with clipping area dis-
abled is located outside the work area. If a part of an object/image is beyond the work area, the drawing
within the work area is performed without an error.
When DRAW_ERR0 is set to 1, a drawing error interrupt request is output to the ITC if GE_ERR_IE0
has been set to 1 (interrupt enabled). An interrupt is generated if the ITC and C33 PE Core interrupt
conditions are satisfied.
DRAW_ERR0 is reset by writing 1.
The GE does not stop command execution even if this error has occurred.
