The
SAMPLE/PRELOAD, BYPASS, and EXTEST. Optional public instructions included are HIGHZ,
CLAMP, and IDCODE. See
Standard Test Access Port and Boundary Scan Architecture.
The DS21354/DS21554 are enhanced versions of the DS2152 and are backward pin compatible. The
JTAG feature uses pins that had no function in the DS2152. When using the JTAG feature, be sure FMS
(pin 76) is tied low, enabling the newly defined pins of the DS21354/DS21554. Details on Boundary
Scan Architecture and the Test Access Port can be found in IEEE 1149.1-1990, IEEE 1149.1a-1993, and
IEEE 1149.1b-1994.
The Test Access Port has the necessary interface pins: JTRST, JTCLK, JTMS, JTDI, and JTDO. See the
