Description
Comments
JP0
LCD Enable/Disable
Normally closed to enable LCD
JP1
ADC V
REF
Input
Normally closed to set V
REF
= 3.3V
JP2
JTAG Debug I/O Pin

2
C access to RTC chip.
JP11
uPSD V
STANDBY
Input
Normally open. Used to enable backup power to uPSD if needed.
JP12
Interrupt Select for MCU
Used to map various Interrupt sources to the MCU. Normally open (see
DK3300 SCHEMATICS, page 7
).
JP13
PWM Channel Select
