DEVICE IDENTIFICATION

80960JD processors may be identified electrically,

according to device type and stepping (see Figure

36, and Table 22 through Table 25). Table 22

identifies the device ID for all 3.3 V and 5 V,

80960JD processors. Figure 36, and Table 23

through Table 25 identify all 3.3 V, 5 V-tolerant,

80960JD processors. The device ID for the C0

stepping is enhanced to differentiate between 3.3 V

and 5 V supply voltages, and between non-clock-

doubled and clock-doubled cores when stepping

from the A2 stepping to the C0 stepping. The 32-bit

identifier is accessible in three ways:

• Upon reset, the identifier is placed into the g0

• The identifier may be accessed from supervisor

mode at any time by reading the DEVICE ID

• The IEEE Standard 1149.1 Test Access Port may

select the DEVICE ID register through the

IDCODE instruction.

• The device and stepping letter is also printed on

the top side of the product package.
