Public instructions
EXTEST (0000)
SAMPLE/PRELOAD (0011)
Instructions are loaded into the TAP state machine by scanning the appropriate bit
pattern for the instruction when the TAP controller is in the SHIFT-IR state, and then
advancing the TAP controller through the UPDATE-IR state.
Table C-1 shows the public instructions.
In the following descriptions, the ARM9E-S samples DBGTDI and DBGTMS on the
rising edge of CLK with DBGTCKEN HIGH. All output transitions on DBGTDO
occur as a result of the rising edge of CLK with DBGTCKEN HIGH.
The EXTEST instruction allows a boundary scan chain to be connected between the
DBGSDIN and DBGSDOUT pins. External logic, based on the DBGTAPSM,
DBGSCREG, and DBGIR signals is required to use the EXTEST function for such a
boundary scan chain. Using EXTEST with scan chain 1 or scan chain 2 selected is
UNPREDICTABLE.
You must use this instruction to preload the boundary scan register with known data
prior to selecting INTEST or EXTEST instructions.
