Simultaneous Display Interface
The DKHiQV-AGP board supports simultaneous flat panel and CRT displays. The HiQVideo™ controllers
supports 60 Hz vertical refresh for simultaneous display CRT and TFT/SSTN color panels. Simultaneous
display of CRT and DDSTN with 60 Hz vertical refresh on the CRT and 120 Hz vertical refresh on the ST-
NDD panel are also supported. In this mode, the ENAVEE(61), ENABKL (54), ACTI (53), M (69) and LP
(68) pins have multiple functions. For detailed functions, and implementations, please refer to the 69000
Databook and the DKHiQV-AGP schematics.
3.3.5
Activity Indicator
The HiQVideo™ controller provides an output pin called ACTI (69000 pin V1) to facilitate an orderly power-
down sequence. The ACTI output is an active high signal which is driven high every time the CPU executes
a valid VGA memory read/write operation or VGA I/O read/write operation. The DKHiQV-AGP board has
an LED (D7) on the ACTI pin which will glow whenever there is a VGA Access. This pin is configured as
Activity Indicator by default when FR0C[4:3]=00. The power management logic may use this signal to put
the HiQVideo™ controller into Panel Off or Standby power modes.
Table 2 summarizes the HiQVideo™ pin connections for the different flat panel configurations.
Refer to the 69000 Databook for the 36-pin panel support information and pin assignments.
