Psc status

psc_status is only valid and applicable when the MCE is powered by a PSA switching supply designed and supplied by UBC.

psc_status is a mas application that decodes the information sent back from the MCE in response to a psc_status command. Usage is:

psc_status -h

 Initial options (MAS config):
       -c <cmd device>         override default command device
       -d         override default data device
       -w <hardware file>      override default hardware configuration file
       -m <MAS config file>    override default MAS configuration file
       -i                      read psc_status as ascii from stdin (no MCE)

The 9 x 32b words returned in response to a psc_status command are described in psc_status.h as:

static char psc_data_blk[PSC_DATA_BLK_SIZE] = "";
