About debug support
Debug clocks
Scan chain 15
Debug support is implemented by using the ARM9EJ-S core embedded within the
ARM926EJ-S processor. Full details of the debug support provided by the ARM9EJ-S
core are described in the ARM9EJ-S Technical Reference Manual.
Debug support for the ARM926EJ-S memory system is implemented by extending the
debug facilities providing access to CP15 using an ARM9EJ-S external scan chain (scan
chain 15). This scan chain is external to the ARM9EJ-S core but internal to the
ARM926EJ-S processor.
The system and test clocks must be synchronized externally to the ARM926EJ-S
macrocell. To synchronize off-chip debug clocking with the ARM926EJ-S macrocell
requires a three-state synchronizer. This is described in the debug chapter of the
ARM9EJ-S Technical Reference Manual.
Scan chain 15 enables access to the CP15 registers. Scan chain 15 is 48 bits long.
Table 11-1 shows the bit assignments for scan chain 15.
With scan chain 15 selected, TDI is connected to bit 47 and TDO is connected to bit 0.
