Description
Enable this bit when operating in full-bridge mode. It affects the modulation high limit.
This value sets the minimum/maximum modulation limits relative to the nominal edge value. The
resolution depends on the switchin g frequency range.
Switching Frequency Range
48.8 kHz to 86.8 kHz
97.7 kHz to 183.8 kHz
195 kHz to 378.8 kHz
390.6 kHz to 625.0 kHz

Description
This register, adding 0 as the MSB, results in a 9-bit OTP threshold value. This 9-bit value is compared to
the nine MSBs of the RTD ADC reading. If the RTD ADC reading is lower than the threshold set by these
bits, the OTP flag is set. This 8-bit register provides 256 threshold settings from 0 mV to 800 mV. One LSB
equates to 800 mV/256 = 3.125 mV. Some of the threshold settings at the high and low ends of the
range are not allowed. The OTP flag has a hysteresis of 16 mV.
