PIC18F2480/2580/4480/4580
DS80496C-page 10  2010 Microchip Technology Inc.
11. Module: ECAN Technology
In Listen Only mode, the module may
persistently set the IRXIF and RXB0IF interrupt
flags, and the RXFUL status flag, after receiving
129 or more consecutive error frames. In this
case, the flags can be cleared, but then will
become set again immediately and continuously
without receiving a bus message.
Work around
Place the ECAN module in Configuration mode
before receiving 129 consecutive error frames
and then place it back into Listen Only mode.

12. Module: 10-Bit Analog-to-Digital
Converter
When the AD clock source is selected as 2 TOSC
or RC (when ADCS<2:0> = 000 or x11), in
extremely rare cases, the E
IL (Integral Linearity
Error) and E
DL (Differential Linearity Error) may
exceed the data sheet specifications at codes,
511 and 512 only.
Work around
Select the AD clock source as 4 TOSC, 8 TOSC,
16 T
OSC, 32 TOSC or 64 TOSC and avoid selecting
2T
OSC or RC.

13. Module: MSSP
In SPI mode, the SDO output may change after
the inactive clock edge of the Bit 0 output. This
may affect some SPI components that read data
over 300 ns after the inactive edge of SCK.
Work around
None.
