Satellite Controller Pin Map
The satellite controller (SC) is responsible for the overall working status of the card. The initial
power sequencing, temperature, and alert signals of power supplies and other ICs are monitored
and controlled completely by the SC. The SC is implemented using a TI MSP432P
microcontroller. The SC is the master of the I2C lines. EEPROM read/write, clock reconfiguration,
and the register settings of the power supply IC are accomplished through this interface. The
major control signals of the SC are summarized in the pin mappings in the following table.
