The MSSP module in I
master and slave functions (including general call
support), and provides interrupts on Start and Stop bits
in hardware to determine a free bus (multi-master
function). The MSSP module implements the standard
mode specifications, as well as 7-bit and 10-bit
addressing.
Two pins are used for data transfer:
• Serial Clock (SCLx) – RC3/SCK1/SCL1 or
• Serial Data (SDAx) – RC4/SDI1/SDA1 or
The user must configure these pins as inputs by setting
the associated TRIS bits.

19.4.1
The MSSP module has six registers for I
These are:
• MSSPx Control Register 1 (SSPxCON1)
• MSSPx Control Register 2 (SSPxCON2)
• MSSPx Status Register (SSPxSTAT)
• Serial Receive/Transmit Buffer Register
• MSSPx Shift Register (SSPxSR) – Not directly
• MSSPx Address Register (SSPxADD)
• MSSPx 7-Bit Address Mask Register (SSPxMSK)
SSPxCON1, SSPxCON2 and SSPxSTAT are the
control and status registers in I
SSPxCON1 and SSPxCON2 registers are readable and
writable. The lower 6 bits of the SSPxSTAT are
read-only. The upper two bits of the SSPxSTAT are
read/write.
SSPxSR is the shift register used for shifting data in or
out. SSPxBUF is the buffer register to which data
bytes are written to or read from.
SSPxADD contains the slave device address when the
MSSP is configured in I
MSSP is configured in Master mode, the lower seven
bits of SSPxADD act as the Baud Rate Generator
reload value.
SSPxMSK holds the slave address mask value when
the module is configured for 7-bit Address Masking
mode. While it is a separate register, it shares the same
SFR address as SSPxADD; it is only accessible when
the SSPM3:SSPM0 bits are specifically set to permit
access.
Section 19.4.3.4 “7-Bit Address Masking Mode”.
In receive operations, SSPxSR and SSPxBUF
together, create a double-buffered receiver. When
SSPxSR receives a complete byte, it is transferred to
SSPxBUF and the SSPxIF interrupt is set.
During
double-buffered. A write to SSPxBUF will write to both
SSPxBUF and SSPxSR.
