Table 5-38. TAP Controller Instructions
Description
Boundary Scan Ring. IEEE 1149.1 specification compliant.
(Mapped twice in IR address space.)
TAP Scan Chain 0 through Chain 28. These are parts of the
internal scan chain subdivided according to a common CCU
clock.
TAP Function Chain 0 through Chain 28. One capture cycle
applied to the individual CCU scan chain clocked by the func-
tional clock.
GeodeLink Address. Access GeodeLink request packet and
data packet control bits.
GeodeLink Data. Access GeodeLink data.
Pad Access. Padtestmode for access to analog and memory
BIST signals.
Program instruction. This instruction provides direct access to
an MSR used for the ROM memory BIST test. Not supported.
GeodeLink Address Action. Same data register as GL_ADDR,
but no GeodeLink transactions are triggered by the access -
only by GLCP debug action.
Test IDDQ. Put chip in a mode for running IDDQ tests.
Revision ID. The TAP instruction used to access the current
revision code (8 bits) for the chip.
TRI-STATE. Put chip into TRI-STATE and comparison mode.
Parallel RAM BIST. Internal data register (for chip test).
ID Code. 0FE1101Fh for the Geode CS5535 companion device.
MSB
ID[31:28]
Version
Bypass. IEEE 1149.1 specification requires all 1s to be
bypassed.
