The EV kit software does not allow writing to the oscillator bits in the Configuration register. How can I write to these bits?
A. The only way to write to these bits with the EVKIT software is to generate a flash file with the oscillator bits set to the desired value. Then, using the EV kit software, perform the “Load Flash from File” operation to write the file into flash. • Q. How critical are the oscillator trim bits in the configuration register? A. The oscillator frequency is not critical for the signal conditioner’s operation. However, the signal conditioner operating speed is a direct function of the oscillator frequency. During the manufacturing process, the oscillator bits in the Configuration register are set so the oscillator frequency is closest to the 1MHz. The default value for the oscillator bits is 000b. • Q. How do I trim the oscillator frequency to 1MHz? A. Using the EV kit software, enable the CLK1M and drive the TEST pin high with VDD. Then connect an oscilloscope to the CLK1M pin and change the OSC[2:0] bits in the Configuration register until the frequency of the signal on the CLK1M pin i
