specifications, as well as 7-bit and 10-bit addressing.
Two pins are used for data transfer. These are the SCK/
SCL pin, which is the clock (SCL), and the SDI/SDA
pin, which is the data (SDA). The user must configure
these pins as inputs or outputs through the
TRISC<5:4> or TRISD<3:2> bits.
The SSP module functions are enabled by setting SSP
Enable bit SSPEN (SSPCON<5>).
FIGURE 19-5:
The SSP module has five registers for I
These are the:
• SSP Control Register (SSPCON)
• SSP Status Register (SSPSTAT)
• Serial Receive/Transmit Buffer (SSPBUF)
• SSP Shift Register (SSPSR) – Not directly
• SSP Address Register (SSPADD)

forces the SCL and SDA pins to be open-drain,
provided these pins are programmed as inputs by
setting the appropriate TRISC or TRISD bits. Pull-up
resistors must be provided externally to the SCL and
SDA pins for proper operation of the I

found in the “PIC
Manual” (DS33023).
19.3.1
In Slave mode, the SCL and SDA pins must be config-
ured as inputs (TRISC<5:4> or TRISD<3:2> 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 is received, the hardware automati-
cally 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 (PIR1<3>), is set.

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. The high and low times of the
I
SSP module, are shown in timing Parameter 100 and
Parameter 101.
