2.1 Power Circuit
Power supply for VDD is selectable by PWR jumper (uEASE/USR).
Power supply for VREF is selectable by VREF jumper (VDD/USR)
Fig.4 Power Circuit
[Note]
When selecting “USR” on the PWR jumper and connecting uEASE, connect the uEASE at first and power up the
user application system the second. As well, power off the user application system at first and power off the uEASE
the second.
When selecting “VREFF” on the VREF jumper and conencting uEASE, connect the uEASE at first and power up the
user application system the second. As well, power off the user application system at first and power off the uEASE
the second.
When selecting “USR” on the MODE jumper, uEASE is not available to use and instead P14/TEST0 pin on the
microcontroller is available to use.
