6 Ground (accessed from test pad pattern and battery connector)
7 Vpp (accessed from test pad pattern)
In HDB15 BB Vpp routing is based on common DCT4 solution. In this solution the use of
higher Vpp voltage is enabled at FLALI phase in production and in after sales if so
wanted.
External voltage (Vpp) is used during flash programming in production and possibly in
aftersales to speed up the process. In production, the usage of external programming
voltage is a necessity but in after sales the usage of external programming voltage does
not necessarily bring any noticeable improvement to flash programming time.
Testing interfaces
In NHL-2NA BB Interfaces Because of Camera, larger memory, sensors there are some
specific testing done and also because of flagship concept there is difference of physical
