bit 6
ST (CT): Start Oscillator (Start Counter) bit
ST (CT) is the oscillator Start bit in the MCP795WXX devices. In the MCP795BXX devices, this bit

starts the RTCC counters. Setting this bit to ‘1’ starts the oscillator and clearing this bit to ‘0’ stops the
on-board oscillator. For the MCP795BXX devices the ST bit is replaced by the CT bit. Setting this bit
starts the timekeeping registers counting.
