Characteristics table, the Min. value for the RPH 3V
was
changed from 40kW
to 20kW
and the Max. value from 80kW

Revision
# 1.80 Modifications made on January 9, 2004
- At the Data
Memory section,
the memory location up to which is reserved for future
expansion was changed from 60H to 30H.
Revision
# 1.71 Modifications made on December 16, 2003
- At the Instruction Set
Summary and Instruction Definition sections, the missing TABRDL [m]
instructions were added back.
Revision
# 1.70 Modifications made on August 27, 2003
- The PD flag label was
changed to PDF flag.
- Inside the INTC0
register table at the Interrupt section, the various labels, EE0I,
EE1I, EI0F and EI1F were changed to EEI0, EEI1, EIF0 and EIF1
respectively.
- The Reset Circuit was
modified.
- The register status
table was modified, particularly the entries for BP, STATUS, INTC0,
RTCC and TMRC. PCH was also deleted.
- At the Options table,
External interrupt trigger edge options for PD4 and PD5 were deleted
and replaced with INT0
or INT1 triggering
edge option.
- The
Application Circuits were modified.
- The recommended RESET circuitry
was modified.
For reasons of stability and noise immunity, the 2-resistor/2-capacitor or 2-resistor/1-capacitor recommended circuits are an improvement over the 1-resistor/1-capacitor circuit. The choice of which circuit is used depends upon the user application. For example, for battery powered applications the single resistor and single capacitor circuit may be adequate whereas for applications such as home appliances, industrial control applications or for circuits which are close to electrical noise sources, the 2-resistor/2-capacitor circuit may be the better choice.
- The Crystal OSC application circuitry
was also modified
The
recommended additional resistor has been added to ensure
that the oscillator will cease to function when the supply
voltage falls below 2.2V to prevent microcontroller
malfunctions. This is because of instabilities in the
oscillator at supply voltages of less than 2.2V.
-
The
RC system oscillator range was changed from 51kW<ROSC<510kW
to
24kW
<ROSC<1MW.
- The Instruction
Definition section was modified, with the first two columns deleted.
