看我是看懂了，但要我翻译，那就太要命了。
Bicephale';s BB0060B maintenance connecter review
A useful set of images with full description..

Preliminary data
~~~~~~~~~~~~~~~~
Our non-invasive incursion into the GNet BB0060B ADSL device begins with
the chip where its FirmWare resides:  U8, an Atmel AT45DB161B FLASH chip
fully described by the chip manufacturer';s 33 pages on-line .PDF manual:
http://www.atmel.fi/dyn/resources/prod_documents/doc2224.pdf （这个是AT45DB161B的说明书）
This document is important in the understanding of the PCB layout around
U8, starting with its TSOP-28 pins layout/description (shown at page 1):
.................. Ready/*Busy -> Rdy/*Busy (1)
....................... *RESET -> *Reset (2)
... HarWare Page Write Protect -> WP (3)
. Voltage (continuous Current) -> Vcc (6)
............... Ground/0 Volts -> Gnd (7)
................. *Chip Select -> *CS (11)
................. Serial Clock -> SCk (12)
................. Serial Input -> SI (13)
................ Serial Output -> SO (14)
................ No Connection -> N.C. (all other pins)
* Marked as "Active Low".

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The alledged Master SCk line coming from between the C43 & R52 locations
is visible here as well, its end just begins past a middle point between
JP1-2 & JP1-3 and makes it look like it connects to JP1-3 at an angle...
