Jumper Descriptions

The jumpers used to configure the MCB54110 board are:

  • J1 VCCAuC: Provides access for measuring analog power consumed by the LPC54114.
  • J1 VCCuC: Provides access for measuring CPU power consumed by the LPC54114.
  • J1 Shunt: Supplies VCC to MCU bypassing R74.
  • VDD_LPC 1V8/3V3: Selects MCU power level 1.8VDC or 3.3VDC.
  • ISP: Selects the booting from ISP via RS232 or from Flash(LINK).
  • RST: Allows MCU Reset from RS232 or from the debug interface(LINK).
  • RXD: MCU is downloaded from RS232 or from the debug interface(LINK).
  • TXD: MCU is downloaded from RS232 or from the debug interface(LINK).
  • MICbias: Connects the left and/or right channel microphone input to the MICBIAS input of the codec. Installing both jumpers produces a monaural input from a stereo microphone.
  • LSP: Connects the loudspeaker amplifier to the digital to analog converter (DAC) output of the MCU.
