Graphics Processor Register Definitions
6.4.2.12 Vector Mode (GP_VECTOR_MODE)
GP Memory Offset 3Ch
Type
Reset Value
Writing to this register configures the vector mode and initiates the rendering of the vector. If a BLT or vector operation is
already in progress when this register is written, the BLT pending bit in GP_BLT_STATUS (GP Memory Offset 44h)is set
and the vector is queued to begin when the current operation is complete. Software should not write to any register (other
than GP_HOST_SRC if required) while the BLT pending bit is set since it will corrupt the pending vector operation. Setting
the TH bit causes the vector operation to wait until the next VBLANK before beginning rendering. Software may still queue
another operation behind a throttled vector as long as the BLT pending bit is clear.
