PIC16(L)F1516/7/8/9
21.6
Master mode is enabled by setting and clearing the
appropriate SSPM bits in the SSPCON1 register and
by setting the SSPEN bit. In Master mode, the SDA and
SCK pins must be configured as inputs. The MSSP
peripheral hardware will override the output driver TRIS
controls when necessary to drive the pins low.
Master mode of operation is supported by interrupt
generation on the detection of the Start and Stop con-
ditions. The Stop (P) and Start (S) bits are cleared from
a Reset or when the MSSP module is disabled. Control
of the I
bus is Idle.
In Firmware Controlled Master mode, user code
conducts all I
Stop bit condition detection. Start and Stop condition
detection is the only active circuitry in this mode. All
other communication is done by the user software
directly manipulating the SDA and SCL lines.
The following events will cause the SSP Interrupt Flag
bit, SSPIF, to be set (SSP interrupt, if enabled):
• Start condition detected
• Stop condition detected
• Data transfer byte transmitted/received
• Acknowledge transmitted/received
• Repeated Start generated

allowed to initiate a Start condition and
immediately write the SSPBUF register to

21.6.1
The master device generates all of the serial clock
pulses and the Start and Stop conditions. A transfer is
ended with a Stop condition or with a Repeated Start
condition. Since the Repeated Start condition is also
the beginning of the next serial transfer, the I
not be released.
In Master Transmitter mode, serial data is output
through SDA, while SCL outputs the serial clock. The
first byte transmitted contains the slave address of the
receiving device (7 bits) and the Read/Write (R/W) bit.
In this case, the R/W bit will be logic ‘0’. Serial data is
transmitted 8 bits at a time. After each byte is transmit-
ted, an Acknowledge bit is received. Start and Stop
conditions are output to indicate the beginning and the
end of a serial transfer.
In Master Receive mode, the first byte transmitted con-
tains the slave address of the transmitting device
(7 bits) and the R/W bit. In this case, the R/W bit will be
logic ‘1’. Thus, the first byte transmitted is a 7-bit slave
address followed by a ‘1’ to indicate the receive bit.
Serial data is received via SDA, while SCL outputs the
serial clock. Serial data is received 8 bits at a time. After
each byte is received, an Acknowledge bit is transmit-
ted. Start and Stop conditions indicate the beginning
and end of transmission.
A Baud Rate Generator is used to set the clock fre-
quency output on SCL. See
