**Obsolete** Virtex JTAG - XAPP139 contains a misprint on the shutdown sequence for AGHIGH command

Description

Keywords: GHIGH

Urgency: Hot

General Description:
(Xilinx XAPP139) contains a misprint on the shutdown sequence. The value of the AGHIGH command is incorrect. This is step 7 on page 10 of (Xilinx XAPP139).

解决方案

NOTE: This issue was corrected in version 1.1 of (Xilinx XAPP139), December 1999.


Page10 of the Application Note has a typo in the shutdown sequence:
http://support.xilinx.com/xapp/xapp139.pdf

The Application Note contains the following:

0011 0000 0000 0000 1000 0000 0000 0001
-> Header: Write to CMD
0000 0000 0000 0000 0000 0000 0000 0100
-> AGHIGH command asserts GHIGH

The AGHIGH command is actually 1000, not 0100.
So the second 32-bit word should be:

0000 0000 0000 0000 0000 0000 0000 1000
