1323x Development Hardware Reference Manual, Rev. 1.0
3-2 Freescale Semiconductor
— 18-Pin secondary connector
— Provide main supply voltage to board
— Provide access to all MC1323x GPIO
• Flexible board power supply
— 3.3 V LDO series regulator supplied
— Regulator bypass jumper option
— Separate external voltage source option
— Power-on green LED
— Jumpers allow various block current measurements
• 6-Pin BDM serial MCU debug port
• MC1323x reset switch
