PIC18F26K20/46K20
Comparators Input Offset Voltage 20. Comparator input offset voltage range
increases as the Common mode
voltage decreases and may degrade
over the lifetime of the part, accelerated
by high temperature.
XX
Comparators Comparator Output 21. The CxOUT is forced to zero when the
CxON bit is clear, irrespective of the
CxPOL bit setting.
XX
Data EEPROM Memory Endurance 22. The write/erase endurance of Data EE
Memory is limited to 10K cycles.
XX
Program Flash Memory Endurance 23. The write/erase endurance of the PFM
is limited to 1K cycles when VDD is
above 3V.
XX
Input/Output
(PIC18F26K20 only)
I/O Pins 24. Reading PORTE bit 3 always returns 0. X X
Timer1 Timer Interrupt 25. False interrupt may occur in
Asynchronous mode.
XX
Timer1/3 Timer Interrupt 26. In Asynchronous mode a false interrupt
may occur if the clock arrives too soon
following a firmware write to the TMR
registers. Also, a switch from
Synchronous to Asynchronous mode
can cause it.
