FDC1004: Offset Calibration Registers format

Part Number: FDC1004

In the datasheet, in §8.6.4, the Offset Calibration Registers are mentioned. bits 15:11 contains the integer part and bits 10:0 the decimal part. It is formatted as a fixed point. I have some doubt on how to program this register.

1/ the range is really -16pF to +16pF, because +16 is not fitting in the integer part as two's complement. Range van -16.00000000000 tot +15.99951171875 pF?

2/ are following examples correct?

a/ -16pF -> register value: 0x8000

b/ +15.99951171875 -> register value: 0x7FFF

c/ -12.4567 -> register value: 0x9C58

Thank you

Jeroen
