to set the B value found in the AN-953 Application Note.
32-bit linear sweep lower limit value. In programmable modulus mode, these bits are used
to set the X value found in the AN-953 Application Note.
Description
32-bit linear sweep decrement step size value.
32-bit linear sweep increment step size value. In programmable modulus mode, these bits
are used to set the A value found in the AN-953 Application Note.
Description
