IN1 and IN2 external inputs

The FRDM-HB2002ESEVM, with a FRDM-KL25Z board (shipped with the kit), can

evaluate the design with a GUI, any MCU with GPIO or with simple lab equipment. A

FRDM-KL25Z compatible GUI and MCU program are available online at the following

link: http://www.nxp.com/FRDM-HB2002ESEVM.

The FRDM-HB2002ESEVM is compatible with any Arduino platform board. However, if a

board other than the FRDM-KL25Z is used, MCU code must be written to work with the

board.

3.5 Input signal definitions

The following input signals control the outputs or functions inside the circuit.
