LEDs indicate the status of the following signals
This EVB has many jumper configurations to evaluate all of the features of the EMC2104/05 .
Fan control can conveniently be evaluated with the onboard 5V fan. Connecting this fan to J3 will allow
full control from the EMC2104/05 via Chipman.
If a 5V 4-wire fan is available, connectors J1 and J2 can be used to evaluate the EMC2104/05 ’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.
