Updated register tables (replaced bitfield data with “-” for bits from 16 to 23) in:
- Section 43.7.6 “AFEC Channel Enable Register”
- Section 43.7.7 “AFEC Channel Disable Register”
- Section 43.7.8 “AFEC Channel Status Register”
- Section 43.7.17 “AFEC Channel Calibration DC Offset Register”
Updated the acronym from ‘AFE’ to ‘AFEC’ in the entire document (except of ‘AFE Controller’).
Updated Section 43.2 “Embedded Characteristics”.
Reworked Section Section 43.6.9 “Input Gain and Offset”:
- updated the first and the last paragraphs
- removed Table 42-7 Offset of the Sample and Hold Unit: OFFSET DIFF and Gain (G)

Register”.
Updated the last paragraph in Section 43.6.3.1 “Enhanced Resolution Mode”.
GMAC:
Replaced "at all three speeds" by "at all supported speeds" in Section 44.1 “Description” and Section 44.2 “Embedded
Characteristics”.
Section 44.7.1 “Network Control Register”, removed the LB bitfield and its description and updated the LBL bitfield
