ARM DDI 0029G
When the BYPASS instruction is loaded into the instruction register, all the scan cells
assume their normal system mode of operation. The BYPASS instruction has no effect
on the system pins:
•
•
•
All unused instruction codes default to the BYPASS instruction.
BYPASS does not enable the processor to exit debug state or synchronize to MCLK for
a system speed access while in debug state. You must use RESTART to achieve this.
In the CAPTURE-DR state, a logic 0 is captured the bypass register.
In the SHIFT-DR state, test data is shifted into the bypass register through TDI
and shifted out through TDO after a delay of one TCK cycle. The first bit to shift
out is a zero.
In the UPDATE-DR state, the bypass register is not affected.
