Struct TARGETID

pub struct TARGETID(pub u32);

TARGETID, Target Identification register (see ADI v5.2 B2.2.10)

TARGETID provides information about the target when the host is connected to a single device.

Tuple Fields

0: u32

Implementations

impl TARGETID

pub fn trevision(&self) -> u8

Target revision.

pub fn tpartno(&self) -> u16

IMPLEMENTATION DEFINED. The value is assigned by the designer of the part. The value must be unique to the part.

pub fn tdesigner(&self) -> u16

IMPLEMENTATION DEFINED.

This field indicates the designer of the part and not the implementer, except where the two are the same. Designers must insert their JEDEC-assigned code here.

Note

The Arm JEP106 value is not shown for the TDESIGNER field. Arm might design a DP containing the TARGETID register, but typically, the designer of the part, referenced in the TPARTNO field, is another designer who creates a part around the licensed Arm IP. If the designer of the part is Arm, then the value of this field is 0x23B.

A JEP106 code takes the following form:

• A sequence of zero or more numbers, all having the value 0x7F.
• A following 8-bit number, that is not 0x7F, and where bit[7] is an odd parity bit. For example, Arm Limited is assigned the code 0x7F 0x7F 0x7F 0x7F 0x3B. The encoding that is used in TARGETID is as follows:
• The JEP106 continuation code, TARGETID bits[11:8], is the number of times that 0x7F appears before the final number. For example, for Arm Limited this field is 0x4.
• The JEP106 identification code, TARGETID bits[7:1], equals bits[6:0] of the final number of the JEDEC code.
