PNX15xx Series provides two groups of high speed pins to stream data or video in
and out. The input group of pins is prefixed by VDI, Video Data Input. The output
group is prefixed by VDO, Video Data Output. Each group is shared between two
modules. On the input side, VIP and FGPI get their pin allocation through the input
router. On the output side QVCP and FGPO get their pin assignment through the
output router. The input router is controlled by VDI_MODE. The output router is
controlled by the VDO_MODE.

Description
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
TM3260 Aperture Modifiable.
This bit is usually written once at boot time.
The value of this bit can only be altered once.
TM3260 Load/Store Unit (i.e. Data Cache) Double Line Fill enable
TM3260 Instruction Fetch Unit (i.e. Instruction Cache) Double Line
Fill enable

Upon writes:
Upon reads
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
0: TM3260 is in full power mode.
1: TM3260 is in full powerdown mode.
• 0: Disables writes by the TM3260 to the MMIO registers
• 1: Enables writes by the TM3260 to the MMIO registers
• 0: Do not enable Double Line fills for the Load/Store Unit
• 1: Enable Double Line fills for the Load/Store Unit
• 0: Do not enable Double Line fills for the Instruction Fetch Unit
• 1: Enable Double Line fills for the Instruction Fetch Unit
• 1->0: Request a TM3260 Power Up
• 0->1: Request a TM3260 Power Down
