FAST OVR THRESH PROG |
Bits 7-0 | FAST OVR THRESH PROG | |
The
device has a fast OVR mode that indicates an overload condition at
the ADC input. The input voltage level at which the overload is
detected is referred to as the threshold and is programmable using
the FAST OVR THRESH PROG bits. FAST OVR is triggered seven output clock cycles after the overload condition occurs. To enable the FAST OVR programmability, enable the EN FAST OVR THRESH register bit. The threshold at which fast OVR is triggered is (full-scale × [the decimal value of the FAST OVR THRESH PROG bits] / 255). After reset, when EN FAST OVR THRESH PROG is set, the default value of the FAST OVR THRESH PROG bits is 230 (decimal). |
