Field descriptions
The PMCIDR3 bit assignments are:
Bits [31:8]
Reserved, RES0.
PRMBL_3, bits [7:0]
Preamble.
Reads as 0xB1.

PMCIDR3 can be accessed through the external debug interface:
Component | Offset | Instance |
---|---|---|
PMU | 0xFFC | PMCIDR3 |
This interface is accessible as follows:
- When FEAT_DoPD is not implemented or IsCorePowered() accesses to this register are RO.
