Device Identification
Table 30.
80960Jx processors may be identified electrically, according to device type and stepping (see
Figure 46, and Table 31 through Table 36). Table 30 identifies the device type and stepping for all
5V, 80960Jx processors. Figure 46, and Table 31 through Table 36 identify all 3.3V-5V-tolerant
80960Jx processors. The device ID was enhanced to differentiate between 3.3V and 5V 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 register.
• The identifier may be accessed from supervisor mode at any time by reading the DEVICEID
register at address FF008710H.
• 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.
