Display Control Unit (DCU)MPC5606S Microcontroller Reference Manual, Rev. 7Freescale Semiconductor 385DISP_ERR occurs when the size of display (height or width) is set to zero or when the pulse width ofhsync/vsync is programmed as zero.SIG_ERR occurs when the area of interest for calculating CRC value is programmed with values whichare outside the display.HWC_ERR occurs if size of cursor programmed is greater than memory size(256x32).See Section 12.4.6,Hardware cursor, for further details on how cursor can be programmed.Figure 12-37.

This can occur if HWC position is out of display area orcursor memory is bigger than the HWC size. When this occurs, the HWC is disabled.14SIG_ERRInterrupt occurs whenever the area of interest specified by SIG_CALC register is outside thedisplay size.0 SIG_ERR is not set1 SIG_ERR is set15DISP_ERRInterrupt occurs whenever width and height of display, pulse width (both vertical and horizontalsync) value is 0.0 DISP_ERR is not set1 DISP_ERR is set16L15_PARR_ERRInterrupt occurs whenever there is an error in layer 15.0 Parameter error is not set1 Parameter error is set
