Feature
3.3V Jumper (1)
This jumper footprint is provided for 3.3V power consumption
measurement use. By default, it is closed. To use this feature,
the user has to open the strap by cutting it before soldering a
jumper.
Forces power on. To use the software shutdown control, J3
must be opened.
Enables Boot on the internal ROM
Enables Boot on the NCS0
VDDPLL Jumper (1)
VDDBU Jumper select (1)
1-2 : Lithium 3V Battery
2-3 : 1.2V from VDDCORE
VDDCORE Jumper (1)
NPCS0 select
1-2: DataFlash device (MN7)
2-3: DataFlash card interface (J22)
Warning: In this case NPCS03 must be configured as
input.
Disables the ICE NTRST input
Enables the ICE RTCK return. S6 must be opened
Enables the ICE NRST input
Selects ICE mode or JTAG mode (See Section 6, Errata )
Disables TCK <-> RTCK local loop. If S6 is closed, S3 must be
opened.
