Description of BOUNDARY-SCAN Circuitry
The scan cells used in the BOUNDARY-SCAN register are
one of the following two types depending upon their loca-
tion. Scan cell TYPE1 is intended to solely observe system
data, while TYPE2 has the additional ability to control sys-
tem data.
Scan cell TYPE1 is located on each system input pin while
scan cell TYPE2 is located at each system output pin as
well as at each of the two internal active-high output enable
signals. AOE controls the activity of the A-outputs while
BOE controls the activity of the B-outputs. Each will acti-
vate their respective outputs by loading a logic high.
The BYPASS register is a single bit shift register stage
identical to scan cell TYPE1. It captures a fixed logic low.

SCAN182541A Product IDCODE
(32-Bit Code per IEEE 1149.1)
The INSTRUCTION register is an 8-bit register which cap-
tures the default value of 10000001 (SAMPLE/PRELOAD)
during the CAPTURE-IR instruction command. The benefit
of capturing SAMPLE/PRELOAD as the default instruction
during CAPTURE-IR is that the user is no longer required
to shift in the 8-bit instruction for SAMPLE/PRELOAD. The
sequence of: CAPTURE-IR
→
EXIT1-IR
→
UPDATE-IR will
update the SAMPLE/PRELOAD instruction. For more infor-
mation refer to the section on instruction definitions.
