PIC18F66K80
Data Sheet Clarifications
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS39977D):
Note:
Corrections are shown in bold. Where
possible, the original bold text formatting
has been removed for clarity.
1. Module: RXFCON Registers
Table 6-1 on Page 116 of the Data Sheet should
show the following register addresses:
E47h-RXFCON1
E46h-RXFCON0
2. Module: RXFCON Registers
Table 6-2 on Page 125 of the Data Sheet should
show the following register addresses:
E47h-RXFCON1
E46h-RXFCON0
3. Module: Listen Only Mode
Page 441, Section 27.3.4 “Listen Only Mode”
will be revised to:
Listen Only mode provides a means for the
PIC18F66K80 family devices to receive all mes-
sages, including messages with errors. This
mode can be used for bus monitor applications
or for detecting the baud rate in ‘hot plugging’
situations. For Auto-Baud Detection, it is neces-
sary that there are at least two other nodes
which are communicating with each other. The
baud rate can be detected empirically by testing
different values until valid messages are
received. The Listen Only mode is a silent
mode, meaning no messages will be transmitted
while in this state, including error flags or
Acknowledge signals. In Listen Only mode,
both valid and invalid messages will be
received regardless of RXMn bit settings.
The filters and masks can still be used to
allow only particular valid messages to be
loaded into the Receive registers, or the filter
masks can be set to all zeros to allow a mes-
sage with any identifier to pass. All invalid
messages will be received in this mode,
regardless of filters and masks or RXMn
Receive Buffer mode bits. The error counters
are reset and deactivated in this state. The
Listen Only mode is activated by setting the
mode request bits in the CANCON register.
