9 (Data EEPROM), 10 (Program Memory), 11 (Core –
DAW Instruction) and 12-18 (EUSART) and Data Sheet
Clarification issue 1 (Power-on Reset).
Rev B Document (2/2004)
Modifications to the Work Around for Silicon issue 3
(PCPWM).
Rev C Document (05/2005)
Added silicon issue 19 (HSADC). All Data Sheet Clarifi-
cation issues were removed and placed into a separate
Data Sheet Errata.
