19 / 104 page  FS401, FS403 PRODUCT SPECIFICATION REV. NO. 1.7 19 JANUARY 24, 2007 COPYRIGHT © 1999 FOCUS ENHANCEMENTS, INC. CCR_MAX_HAT Maximum Horizontal Active CCR_DEF_SVV Default Start of Vertical Video CCR_MIN_SVV Minimum Start of Vertical Video CCR_MAX_SVV Maximum Start of Vertical Video CCR_DEF_VAT Default Vertical Active CCR_MIN_VAT Minimum Vertical Active CCR_MAX_VAT Maximum Vertical Active An external controller can reset the input calibration and force the internal micro-controller to reacquire the input calibration information by setting the RSTICAL bit in the SCR register. 4.2.1.2 Manual Input Calibration The auto input calibration can be by-passed by setting the DSICAL bit in the SCR register. When DSICAL is set, the internal micro-controller will use the manual input calibration values. An external controller can modify the manual input calibration values by changing the following configuration values via the CCR and CDR registers: CCR_SHV Start of Horizontal Video CCR_HAT Horizontal Active CCR_SVV Start of Vertical Video CCR_VAT Vertical Active The external controller must set the MICALNEW bit in the SCR register after each change to the manual input calibration values. The internal controller will not recognize a change in the state of DSICAL until the next video mode change or until the RSTICAL bit in the SCR register is set. The manual input calibration values do not change when a new video mode is detected, except when Input Calibration Tables are enabled. If an external processor needs to write different manual input calibration information for new video modes, it must poll the MCC bit in the SSR register to determine when a new video mode is present. Next, the external processor can read the CCR_IVC and CCR_IHC configuration values to determine the new video mode and then write the appropriate input calibration information.
