tion of data. When transmitting data, one device is the “master” which initiates transfer on the bus
and generates the clock signals to permit that transfer, while the other device(s) acts as the
“slave.” All portions of the slave protocol are implemented in the SSP module’s hardware, except
general call support, while portions of the master protocol need to be addressed in the
PIC16CXX software. The MSSP module supports the full implementation of the I
tocol, the general call address, and data transfers upto 1 Mbps. The 1 Mbps data transfers are
supported by some of Microchips Serial EEPROMs.
minology.
In the I
transfer, it first transmits the address of the device that it wishes to “talk” to. All devices “listen” to
see if this is their address. Within this address, a bit specifies if the master wishes to
read-from/write-to the slave device. The master and slave are always in opposite modes (trans-
mitter/receiver) of operation during a data transfer. That is they can be thought of as operating in
either of these two relations:
• Master-transmitter and Slave-receiver
• Slave-transmitter and Master-receiver
In both cases the master generates the clock signal.
The output stages of the clock (SCL) and data (SDA) lines must have an open-drain or open-col-
lector in order to perform the wired-AND function of the bus. External pull-up resistors are used
to ensure a high level when no device is pulling the line down. The number of devices that may
