Dual Cluster System Auxiliary Platform ID Register, DCS_AID

The read-only DCS_AID register returns information about the platform to the Versatile Express platform configuration controller.

It also contains other status fields that software or users of the platform can use. The following table shows the bit assignments.

Table 3-38 DCS_AID Register bit assignments

Bits Name Type Description
[31:24] BUILD RO A serial build number for all DCS releases, starting at zero. The build number uniquely identifies each platform.
[23:14] - RO Reserved. RAZ.
[13:12] INTGEN_INTS RO

Number of interrupts that the interrupt generation trickbox controls:

0b0032 interrupts.
0b0164 interrupts.
0b1096 interrupts.
0b11128 interrupts.
[11] INTGEN_PRESENT RO

Reads as:

1If the interrupt generation trickbox is present.
0Otherwise.
[10] SW_ENABLE RO

Reads as:

1If the platform supports reading switch or configuration inputs from the DCS_SW register.
0Otherwise.
[9] LED_ENABLE RO

Reads as:

1If the platform supports setting LEDs or status information through the DCS_LED register.
0Otherwise.
[8] - RO Reserved. RAZ.
[7:0] CFGREGNUM RO Reads as zero to indicate that no additional Versatile Express user-defined configuration commands exist.

The BUILD field identifies a specific release of a dual cluster system platform implementation. No two releases of a platform implementation have a same build number, regardless of the version of the system specification that it implements. Build numbers are only unique within a particular implementation, and there is no relationship between build numbers of different platform implementations. For example, an FPGA implementation with a build number of 0x8'h05 is not necessarily based on the same dual cluster system source version as build number 0x8'h05 of a software model.
