System Control 

The emPC-CXR provides some features for system control and supervision.  Refer to figure 3 for the 
relevant components: 

•

 

The  system  MCU  which  controls  the  power  supply  and  COM  express  module  run  state. 
Controlled  either  by  the  power  supply  voltage  or  by  the  control  input  (mid  pin  on  the  power 
supply connector). 

•

 

The  system  MCU  provides  an  I2C  slave  interface  on  the  host  I2C  to  monitor  and  modify 
system operation. 

•

 

Access  to  the  host  I2C  bus  is  possible  by  a  I2C  master  interface  which  is  provided  by  the 
FPGA subsystem. 

•

 

A digital temperature sensor is available and can be read via the system MCU. 

•

 

The  ispPAC  power  sequencer  which  controls  and  monitors  the  internal  power  supplies.  The 
integrated ADC can check any of the internal voltages and might be read via the system MCU.
