DEVICE IDENTIFICATION

80960JD processors may be identified electrically according to device type and stepping (see Table 23). 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.

NOTE:

This data sheet applies to the 80960JD A and 80960JD A2 steppings.
