PTH jumper description:
CPE
NTRST_E
WP_SFLASH_E
WP_NFLASH_E
A2_L/A2_H Connects Address2(A2)pin of U8-24LC256 memory (default not
BAT/EXT
INTRC/EXTCLK
BMS_LOW
Connects PC8(pin61) to Card Present pin of SD/MMC socket.
If CP function is not used, CPE jumper has to be open and
PC8 is available of EXT connector pin 14.
Default state - closed
When the NTRST_E jumper is closed – connects NTRST(pin 35)
to JTAG connector (pin3).
Default state - closed
closed it allows to protect the boot code written to
U5(AT45DB161D-SU) flash memory.
Default state open
closed user can't write in the NAND flash.
Default state open
mounted) to logical 0 or logical 1, i.e. A2_L/A2_H define the
memory address of I2C bus.
Default state - open
Default state - open
The BATerry/EXTernal jumper defines the power source which
supplies the backup logic from VDDBU - pin 47.
BAT position – 3V Li battery type CR2032 plugged in BAT
holder
MCP1700T-1802E/MB voltage regulator.
EXT position – The VDDBU is powered from main 1.8V voltage
regulator VR2(1.8V) – LM1117.
Default state
The INTRC/EXTCLK jumper defines the SAM9260 slow clock
source.
INTRC position – internal RC slow clock oscilator is selected
EXTCLK position – external 32768 crystal is used for
SAM9260 slow clock.
Boot Mode Sellect _ LOW jumper select the boot memory
External memory or embedded ROM. When BMS_LOW is
closed – BMS pin is logical 0, otherwise – logical 1.
