JTAG (1149.1) TESTING
The M7010R supports the Test Access Port (TAP)
and Boundary Scan Architecture as specified in
the IEEE JTAG standard 1149.1. The pin interface
to the chip consists of five signals with the stan-
dard definitions: TCK, TMS, TDI, TDO, and
TRST_L. Table 38, page 62 describes the opera-
tions that the test access port controller supports.
Table 39 shows the TAP Device ID Register.
Note: To disable JTAG functionality, connect the
TCK, TMS, and TDI pins to VDDQ through a pull-
up, and the TRST_L to ground through a pull-
down.

Instruction
Type
Description
SAMPLE/PRELOAD
Mandatory
Sample/Preload. Loads the values of signals going to and from IO
pins into the boundary scan shift register to provide a snapshot of the
normal functional operation.
EXTEST
Mandatory
External Test. Uses boundary scan values shifted in from TAP to test
connectivity external to the device.
INTEST
Optional
Internal Test. Allows slow-speed, functional testing of the device
using the boundary scan register to provide the I/O values.
