14.11 SSP I
The SSP module in I
functions, except general call support, and provides
interrupts on Start and Stop bits in hardware to facilitate
firmware implementations of the master functions. The
SSP
specifications, as well as 7-bit and 10-bit addressing.
Two pins are used for data transfer. These are the
RC6/TX/CK/SCK/SCL/SEG9 pin, which is the clock
(SCL), and the RC7/RX/DT/SDI/SDA/SEG8 pin, which
is the data (SDA).
The SSP module functions are enabled by setting SSP
enable bit SSPEN (SSPCON<5>).
FIGURE 14-7:
The SSP module has five registers for the I
which are listed below.
• SSP Control register (SSPCON)
• SSP STATUS register (SSPSTAT)
• Serial Receive/Transmit Buffer (SSPBUF)
• SSP Shift register (SSPSR) – Not directly
• SSP Address register (SSPADD)

The SSPCON register allows control of the I
operation. Four mode selection bits (SSPCON<3:0>)
allow one of the following I
• I
• I
• I
• I
• I
Selection of any I
forces the SCL and SDA pins to be open drain,
provided these pins are programmed to inputs by
setting the appropriate TRISC bits. Pull-up resistors
must be provided externally to the SCL and SDA pins
for proper operation of the I
14.12 Slave Mode
In Slave mode, the SCL and SDA pins must be
configured as inputs (TRISC<7,6> are set). The SSP
module will override the input state with the output data
when required (slave-transmitter).
When an address is matched, or the data transfer after
an address match
automatically will generate the Acknowledge (ACK)
pulse, and then load the SSPBUF register with the
received value currently in the SSPSR register.
There are certain conditions that will cause the SSP
module not to give this ACK pulse. They include (either
or both):
a)
b)
In this case, the SSPSR register value is not loaded
into the SSPBUF, but bit SSPIF of the PIR1 register is
set. Table 14-3 shows the results of when a data
transfer byte is received, given the status of bits BF and
SSPOV. The shaded cells show the condition where
user software did not properly clear the overflow
condition. Flag bit BF is cleared by reading the
SSPBUF register, while bit SSPOV is cleared through
software.
The SCL clock input must have a minimum high and low
for proper operation. For high and low times of the I
specification, as well as the requirements of the SSP
module, see Section 19.0 “Electrical Specifications”.
