Scan chain 2
Purpose
Length
Scan chain order
No action occurs during CAPTURE-DR.
During SHIFT-DR, a data value is shifted into the serial register. Bits 32 to 36 specify
the address of the EmbeddedICE register to be accessed.
During UPDATE-DR, this register is either read or written depending on the value of
bit 37 (0 = read, 1 = write).
Copyright © 2000 ARM Limited. All rights reserved.
Scan chain 2 allows access to the EmbeddedICE registers. To do
this, scan chain 2 must be selected using the SCAN_N instruction,
and then the TAP controller instruction must be changed to
INTEST.
38 bits.
From DBGTDI to DBGTDO. Read/write, register address bits 4
to 0, data values bits 31 to 0.
