PIC18F2515/2610/4515/4610
The PIC18F2515/2610/4515/4610 Rev. A3 parts you
have received conform functionally to the Device Data
Sheet (DS39636C), except for the anomalies
described below. Any Data Sheet Clarification issues
related to the PIC18F2515/2610/4515/4610 will be
reported in a separate Data Sheet errata. Please check
the Microchip web site for any existing issues.
The following silicon errata apply only to
PIC18F2515/2610/4515/4610 devices with these
Device/Revision IDs:
1. Module: MSSP
In its current implementation, the I
2
C™ Master
mode operates as follows:
a) The Baud Rate Generator for I
2
C in Master
mode is slower than the rates specified in
Table 16-3 of the Device Data Sheet.
For this revision of silicon, use the values
shown in Table 1 in place of those shown in
Table 16-3 of the Device Data Sheet. The
differences are shown in bold text.
b) Use the following formula in place of the
one shown in Register 16-4 (SSPCON1) of
the Device Data Sheet for bit description
SSPM3:SSPM0 = 1000.
SSPADD = INT((F
CY/FSCL) – (FCY/1.111 MHz)) – 1
