Processor Data Sheet
While in the Shift-DR state, the BSR shift register is serially
shifted toward the TDO pin. During the shift, bit 280 of the
BSR is loaded from the TDI pin.
The BSR output register is loaded with the contents of the BSR
shift register in the Update-DR state. If the current instruction
is EXTEST, the processor’s output pins, as well as those
bidirectional pins that are enabled as outputs, are driven with
their corresponding values from the BSR output register.
