Notes:
6. Irange: Isinkn(15)/ Isinkn(0) for the same pin.
7. Tratio = Isink1[1:0](n)/Isink0[7:2](n) for the same n, programmed.
8. Ilin measured as largest step size vs. nominal according to measured full scale and zero programmed values.
9. Per Table 7-6 of revision 1.1 of USB specification.
10. For 25-pF load.
11. Assumes chip select CS is asserted (LOW).
