THE OVD HIGH/LOW LEVEL DAC IS SHARED BY EACH CHANNEL; THEREFORE, ONLY ONE OVD HIGH/LOW VOLTAGE
THIS IS A READ ONLY REGISTER THAT ALLOWS THE USER TO DETERMINE THE CAUSE OF THE ACTIVE OVD FLAG.
LEVEL CAN BE SET PER CHIP. THE OVD DACs PROVIDE A VOLTAGE RANGE OF –3V TO +7V. THE RECOMMENDED
HIGH/LOW SETTINGS ARE +6.5V/–2.5V. (THESE VALUES NEED TO BE PROGRAMMED BY THE USER UPON STARTUP/RESET.)
