GeodeLink™ Control Processor
6.13
The GeodeLink Control Processor (GLCP) functionality
covers these areas (see Figure 6-55):
• Scan chain control
• JTAG interface to boundary scan, BIST, GLIU1, and
• Power (clock) control
• Reset logic
• PLL control
• Internal logic analyzer/debugger
• 1KB FIFO/SRAM
• Compliant with GLIU System Architecture Specification
• Supports AMD Geode™ CS5536 companion device
• Supports physical pins for SUSPA# and IRQ13
• Supports muxed pin for SUSP#

6.13.1
The TAP controller is IEEE 1149.1 compliant. TMS, TDI,
TCLK, and TDO are directly supported (TRST is available
as a bootstrap pin during reset, but is always inactive if the
system reset is inactive). The Instruction register (IR) is 25
bits wide. The meanings of the various instructions are
shown in Table 6-81 on page 534 along with the length of
the Data register that can be accessed once the instruction
is entered. All Data registers shift in and out data, LSB first.
The Instruction and all Data registers are shift registers, so
if more bits are shifted in than the register can hold, only
the last bits shifted in (the MSBs) are used.
The TAP controller has specific pre-assigned meanings to
the bits in the 25-bit IR. The meanings are summarized in
Table 6-82 on page 534. Note that the bits only affect the
chip once the “Update-IR” JTAG state occurs in the JTAG
controller. Shifting through these bits does not change the
state of internal signals (for example TEST_MODE). For
details on JTAG controller states, refer to the IEEE Stan-
dard 1149.1-1990.
