2.3 Jumper settings
2.3.1 JP1
JP1 is a switch jumper to select the power supply.
2.3.2 JP2
JP2 is the point to measure consumption current of microcontroller AVREFP terminal. Take off short pin and
connect an ampere meter to measure the current. As the sample software uses VREFOUT, take off the
short pin. It is opened as default.
2.3.3 JP3
JP3 is the point to measure consumption current of microcontroller AVDD0 terminal. Take off short pin and
connect an ampere meter to measure the current. It is shorted as default.
2.3.4 JP4
JP4 is the point to measure consumption current of microcontroller AVDD1 terminal. Take off short pin and
connect an ampere meter to measure the current. It is shorted as default.
2.3.5 JP5
JP5 is the point to measure consumption current of microcontroller VDD terminal. Take off short pin and
connect an ampere meter to measure the current. It is shorted as default.
2.3.6 JP6
JP6 is the point to measure consumption current of microcontroller EVDD terminal. Take off short pin and
connect an ampere meter to measure the current. It is shorted as default.
2.4 Connector
2.4.1 FP1
This is the interface to connect MINICUBE2.
The connector itself is not attached. If you wish to connect MINICUBE2, you need to solder the 16pin
connector on FP1.
2.5 Clock
2.5.1 Y1
This is the main clock. 20MHz Ceralock (Murata: CSTLS20M0X51-B0) is mounted.
2.5.2 Y2
This is the sub clock. 32.768KHz oscillator (SII: SSP-T7-FL 3.7pF) is mounted.
