17.1.2
SLAVE MODE
For any SPI device acting as a slave, the data is
transmitted and received as external clock pulses
appear on SCK pin. This external clock must meet the
minimum high and low times as specified in the
electrical specifications.
17.1.2.1
Slave Mode Operation
The SSP consists of a transmit/receive shift register
(SSPSR) and a buffer register (SSPBUF). The SSPSR
shifts the data in and out of the device, MSb first. The
SSPBUF holds the data that was written to the SSPSR
until the received data is ready.
The slave has no control as to when data will be
clocked in or out of the device. All data that is to be
transmitted, to a master or another slave, must be
loaded into the SSPBUF register before the first clock
pulse is received.
Once eight bits of data have been received:
Received byte is moved to the SSPBUF register
BF bit of the SSPSTAT register is set
SSPIF bit of the PIR1 register is set
Any write to the SSPBUF register during transmission/
reception of data will be ignored and the Write Collision
Detect bit, WCOL of the SSPCON register, will be set.
User software must clear the WCOL bit so that it can be
determined if the following write(s) to the SSPBUF
register completed successfully.
The user’s firmware must read SSPBUF, clearing the
BF flag, or the SSPOV bit of the SSPCON register will
be set with the reception of the next byte and
communication will be disabled.
A SPI module transmits and receives at the same time,
occasionally causing dummy data to be transmitted/
received. It is up to the user to determine which data is
to be used and what can be discarded.
17.1.2.2
Enabling Slave I/O
To enable the serial port, the SSPEN bit of the
SSPCON register must be set. If a Slave mode of
operation is selected in the SSPM bits of the SSPCON
register, the SDI, SDO and SCK pins will be assigned
as serial port pins.
For these pins to function as serial port pins, they must
have their corresponding data direction bits set or
cleared in the associated TRIS register as follows:
SDI configured as input
SDO configured as output
SCK configured as input
Optionally, a fourth pin, Slave Select (SS) may be used
in Slave mode. Slave Select may be configured to
operate on the RC6/SS pin via the SSSEL bit in the
APFCON register.
Upon selection of a Slave Select pin, the appropriate
bits must be set in the ANSELA and TRISA registers.
Slave Select must be set as an input by setting the
corresponding bit in TRISA, and digital I/O must be
enabled on the SS pin by clearing the corresponding bit
of the ANSELA register.
17.1.2.3
Slave Mode Setup
When initializing the SSP module to SPI Slave mode,
compatibility must be ensured with the master device.
This is done by programming the appropriate control
bits of the SSPCON and SSPSTAT registers. These
control bits allow the following to be specified:
SCK as clock input
Idle state of SCK (CKP bit)
Data input sample phase (SMP bit)
Output data on rising/falling edge of SCK (CKE bit)
Figure 17-4 and Figure 17-5 show example waveforms
of Slave mode operation.
