17.4
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 (SCL) – SCK/SCL
• Serial data (SDA) – SDI/SDA
The user must configure these pins as inputs with the
corresponding TRIS bits.

17.4.1
The MSSP module has seven registers for I
operation. These are:
• MSSP Control Register 1 (SSPCON1)
• MSSP Control Register 2 (SSPCON2)
• MSSP STATUS register (SSPSTAT)
• Serial Receive/Transmit Buffer Register
• MSSP Shift Register (SSPSR) – Not directly
• MSSP Address Register (SSPADD)
• MSSP Address Mask (SSPMSK)
SSPCON1, SSPCON2 and SSPSTAT are the control
and STATUS registers in I
SSPCON1 and SSPCON2 registers are readable and
writable. The lower 6 bits of the SSPSTAT are read-only.
The upper two bits of the SSPSTAT are read/write.
SSPSR is the shift register used for shifting data in or
out. SSPBUF is the buffer register to which data bytes
are written to or read from.
When the SSP is configured in Master mode, the lower
seven bits of SSPADD act as the Baud Rate Generator
reload value. When the SSP is configured for I
mode the SSPADD register holds the slave device
address. The SSP can be configured to respond to a
range of addresses by qualifying selected bits of the
address register with the SSPMSK register.
In receive operations, SSPSR and SSPBUF together
create a double-buffered receiver. When SSPSR
receives a complete byte, it is transferred to SSPBUF
and the SSPIF interrupt is set.
During
double-buffered. A write to SSPBUF will write to both
SSPBUF and SSPSR.
