32.4. Switch IP Registers

Each register is either read-only (RO) or read-write (RW).

Table 577.  Switch IP RegistersIn the software API the register names appear with a prefix of INTEL_VVP,INTEL_VVP_CORE, or INTEL_VVP_VIDEO SWITCH as appropriate and with an optional REG suffix.
Address Register Access Description
Parameterization registers
0x0000 PROD_ID RO Read this register for the Switch IP product ID. This register always returns 0x6AF7_0235
0x0004 VERSION RO Read this register for the version information for the Switch.
0x0008 INTF_TYPE RO

Read this register to determine the interface type. This register returns:

  • 0 when you select Full interfaces.
  • 1 when you select Lite interfaces.
  • 2 when you select full raster interfaces.
0x000C DEBUG_ENABLED RO Read this register to determine if Debug features are on.
0x0010 UNINTERRUPTED_INPUTS RO Read this register to determine if All inputs are uninterrupted is on.
0x0014 AUTO_CONSUME RO Read this register to determine if Autoconsume is on.
0x0018 NUM_INPUTS RO Read this register to determine the number of configured inputs.
0x001C NUM_OUTPUTS RO Read this register to determine the number of configured outputs.
0x0020 USE_TREADIES RO Read this register to determine if ‘tready’ signal present on switch streaming interfaces is on.
0x0024 CRASH SWITCH RO Read this register to determine if Crash switching is on.
0x0028 to 0x011F RESERVED - Unused.

Control and debug registers

For more details of these registers, refer to Control Packets

0x0120 to 0x13F RESERVED - Unused.
0x0140 STATUS RO

Bit 0: Goes low when a switch starts and returns high when switching completes

Bit 1: Pending run-time control bit. Goes high when a write occurs to one of the input or output control registers. Goes low after a write to the COMMIT register and the IP switch starts the switch.

0x0144 COMMIT RW Write 1 to bit 0 to commit the control register settings and request a new switch. The new switch starts immediately if no switch is currently in progress, otherwise it starts when the current switch completes.
0x0148 INPUT_CONTROL_0 RW 85

Each input has a control register. The IP uses the two input LSBs for control, decoded as follows:

  • 00: disable. Drive TREADY low and do not propagate data.
  • 01: enable. If one of the output registers is configured to receive or consume this input, data propagates, otherwise TREADY is low.
  • 10: disable. Drive TREADY low and do not propagate data.
  • 11: consume. Drive TREADY high but do not propagate data.
0x014C INPUT_CONTROL_1 RW85
0x0150 INPUT_CONTROL_2 RW85
0x0154 INPUT_CONTROL_3 RW85
0x0158 INPUT_CONTROL_4 RW85
0x015C INPUT_CONTROL_5 RW85
0x0160 INPUT_CONTROL_6 RW85
0x0164 INPUT_CONTROL_7 RW85
0x0168 to 0x187 RESERVED - Reserved.
0x0188 OUTPUT_CONTROL_0 RW85

Set bit[8] to enable an output.

Set bits [7:0] to give the integer value of the input to drive the output. An out-of-range input value has the effect of disabling the output.

Inputs and outputs start at zero.

For example, a write of 0x104 to an output control register enables the output and selects input number 4. If the two LSBs in INPUT_CONTROL_4 are 01, the IP enables the connection and input number 4 drives the output.

0x018C OUTPUT_CONTROL_1 RW85
0x0190 OUTPUT_CONTROL_2 RW85
0x0194 OUTPUT_CONTROL_3 RW85
0x0198 OUTPUT_CONTROL_4 RW85
0x019C OUTPUT_CONTROL_5 RW85
0x01A0 OUTPUT_CONTROL_6 RW85
0x01A4 OUTPUT_CONTROL_7 RW85
0x01A8 to 0x01C4 RESERVED - Reserved.
