21.3 JTAG Registers

21.3.2 Data Register

(1) Boundary Scan Register (JTAGBSR)

The Boundary Scan Register is a 294-bit register used to perform boundary-scan test. The bits in this

Connected between the JTDI and JTDO pins, this register is selected when issuing EXTEST or

SAMPLE/PRELOAD instruction. In the Capture-DR state, this register captures the status of input

pins or internal logic outputs. In the Shift-DR state, while outputting the sampled value, this register

receives the input data for boundary-scan test to set pin functions (direction of input/output and

tristate output pins) and output values.

(2) Bypass Register (JTAGBPR)

The Bypass Register is a 1-bit register used to bypass the boundary-scan path when the microcom-

puter is not the target of boundary-scan test. Connected between the JTDI and JTDO pins, this regis-

ter is selected when issuing BYPASS instruction. This register is loaded with b’0 (fixed value) in the

Capture-DR state.

(3) ID Code Register (JTAGIDR)

The ID Code Register is a 32-bit register used to identify the device and manufacturer. It holds the

following information:

Version information (4 bits)

Part number (16 bits)

: b'0011 0010 0010 0111 (32185)

: b’0011 0010 0010 0110 (32186)

Manufacturer ID (11 bits)

: b’010 0010 0011

This register is connected between the JTDI and JTDO pins, and is selected when issuing IDCODE

instruction. This register is loaded with said IDCODE data in the Capture-DR state, and outputs it from

the JTDO pin in the Shift-DR state.

The ID Code Register is a read-only register. Because the data written from the JTDI pin during DR

path sequence is ignored, make sure JTDI input = "L" while in the Shift-DR state.

Note: For details about the Capture-DR and Shift-DR states, see Section 21.4, “Basic Operation of JTAG.”
