IDENTIFICATION REGISTER
The identification register contains a 32-bit shift register and a 32-bit latched parallel output. This
register is selected during the IDCODE instruction and when the TAP controller is in the Test-Logic-
Reset state. See Table 19-2. Table 19-3 lists the device ID codes for the SCT devices.
