Detailed Description

VME device that monitors voltages on LVMB and powers on/off DCFEBs+ALCT.

Supported VME commands:

W 8000 write control byte to ADC, format below
R 8004 read ADC
W 8010 set DCFEB/ALCT power-on signals
R 8014 read DCFEB/ALCT power-on status (ODMB firmware)
R 8018 read DCFEB/ALCT power-on status from LVMB
W 8020 select ADC to read
R 8024 read which ADC is selected
W 801C temporary debugging command to keep PON_LOAD asserted (1) or de-asserted (0) Control byte format
bit 7 START - 1 to initiate read
bit 6-4 SEL - select channel to read
bit 3 RNG - 1 to go up to 10V, 0 for 5V
bit 2 BIP - 0 for only positive voltages, 1 for negative (+-5V or +-10V)
bit 1-0 PD - mode select 00 normal internal clock, 11 normal external clock, 10 standby, 11 power down
