Operating
(SSPM3:SSPM0 = 0110), the MSSP module of
this silicon version may not send a NACK bit (ACK)
in response to receiving the slave address loaded
in SSPADD<7:1>.
The affected addresses are in the following
ranges:
• 0x00 to 0x07
• 0x78 to 0x7F (available when using 10-bit slave
These addresses are reserved, as specified in
“I
Revision 03, 19 June 2007. Section 3.12,
“Reserved Addresses”, defines the purposes of
these addresses.
The specification is available at:
Work around
Do either of the following:
• Change the 7-bit slave address in SSPADD to
• Use Revision B silicon
