the INTOSC stabilization delay from 1 ms to 4 ms in
Section 4.0 “Oscillator Configurations”. Updated
Section 12.17 “In-Circuit Serial Programming” to
clarify LVP programming. In Section 15.0 “Electrical
Characteristics”, the DC Characteristics (Section 15.2
and Section 15.3) have been updated to include the
Typ, Min and Max values and Table 15-1 “External
Clock Timing Requirements” has been updated.
Revision E (September 2004)
This revision includes the DC and AC Characteristics
Graphs and Tables. The Electrical Specifications in
