Description
These reflect the current state of the TAP controller state machine. These
bits change on the rising edge of TCK.
See Figure B-2 on page B-5.
When LOW, D[31:0], A[31:0], LOCK, MAS[1:0], nRW, nTRANS,
and nOPC are set to high impedance.
Similar in effect as if both ABE and DBE had been driven LOW.
However, TBE does not have an associated scan cell and so allows
external signals to be driven high impedance during scan testing.
Under normal operating conditions TBE must be HIGH.
When the processor is executing the THUMB instruction set, this is
HIGH. It is LOW when executing the ARM instruction set.
This signal changes in phase two in the first execute cycle of a BX
instruction.
Clock signal for all test circuitry. When in debug state, this is used to
generate DCLK, TCK1, and TCK2.
HIGH when TCK is HIGH (slight phase lag due to the internal clock
non-overlap).
HIGH when TCK is LOW (slight phase lag due to the internal clock
non-overlap).
It is the non-overlapping complement of TCK1.
Serial data for the scan chains.
Serial data from the scan chains.
Mode select for scan chains.
Provide power to the device.
These connections are the ground reference for all signals.
