LEDs indicate the status of the following signals
This EVB has many jumper configurations to evaluate all of the features of the EMC2106.
Fan control can conveniently be evaluated with the onboard 5V fan. Connecting this fan to J3 will allow
full control from the EMC2106 via Chipman.
If a 5V 4-wire fan is available, connectors J1 and J2 can be used to evaluate the EMC2106’s ability
to drive and control these types of fans. If PWM1 is to control the 4-wire fan, the appropriate register
in Chipman should be set. If PWM2 is desired to drive a 4-wire 5V fan, J2 should be used. In addition,
JP18 must be in postion 2-3 and JP7 in Position 2-3.
