Peripheral identification register byte. Returns byte of the peripheral ID. The PIDR4 register is part of the set of peripheral identification registers.
The PIDR4 register characteristics are:
|Usage constraints||There are no usage constraints.
|Configurations||There is only one configuration.
The following figure shows the bit assignments.
3-18 PIDR4 register bit assignments
The following list shows the register bit assignments.
|[7:4] SIZE||Indicates that the GFC-100 registers occupy a single 4KB page.
|[3:0] DES_2||Indicates how many Continuation Codes (
0x7F) an Arm device requires. For identifying an Arm device or product, the Standard Manufacturer’s Identification Code specifies a requirement of four Continuation Codes.
