Battery Connector BAT1
The mounting space BAT1 (see PCB stencil) is provided for
connection of a battery that buffers volatile memory devices (SRAM)
and the RTC on the phyCORE-167CR/167CS. The Voltage
Supervisor Chip on the phyCORE-167CR/167CS is responsible for
switching from a normal power supply to a back-up battery. The
optional battery required for this function (refer to section 11) is
available through PHYTEC (order code BL-003).

Releasing the /NMI Interrupt
The boot button S1 on the phyCORE Development Board HD200 can
be routed to the non-maskable interrupt (/NMI) of the
C167CR/C167CS controller with applicable configuration of Jumper
JP28 (also refer to section 14.3.2).

DS2401 Silicon Serial Number
Communication to a DS2401 Silicon Serial Number can be
implemented in various software applications for the definition of a
node address or as copy protection in networked applications. The
DS2401 can be soldered on space U10 or U9 on the Development
Board, depending on the type of device packaging being used.
The Silicon Serial Number Chip mounted on the phyCORE
Development Board HD200 can be connected to port pin P2.1 of the
C167CR/C167CS available at GPIO1 (JP19 = closed).
