16.0
The Serial Peripheral Interface (SPI) module is a syn-
chronous serial interface. It is useful for communicating
with other peripheral devices such as EEPROMs, shift
registers, display drivers and A/D converters, or other
microcontrollers. It is compatible with Motorola's SPI
and SIOP interfaces.
16.1
Each SPI module consists of a 16-bit shift register,
SPIxSR (where x = 1 or 2), used for shifting data in
and out, and a buffer register, SPIxBUF. A control reg-
ister, SPIxCON, configures the module. Additionally, a
status register, SPIxSTAT, indicates various status
conditions.
The serial interface consists of 4 pins: SDIx (serial
data input), SDOx (serial data output), SCKx (shift
clock input or output), and SSx (active low slave
select).
In Master mode operation, SCK is a clock output, but
in Slave mode, it is a clock input.
A series of eight (8) or sixteen (16) clock pulses shifts
out bits from the SPIxSR to SDOx pin and simulta-
neously shifts in data from SDIx pin. An interrupt is
generated when the transfer is complete and the cor-
responding interrupt flag bit (SPI1IF or SPI2IF) is set.
This interrupt can be disabled through an interrupt
enable bit (SPI1IE or SPI2IE).
The receive operation is double buffered. When a
complete byte is received, it is transferred from
SPIxSR to SPIxBUF.
If the receive buffer is full when new data is being
transferred from SPIxSR to SPIxBUF, the module will
set the SPIROV bit, indicating an overflow condition.
The transfer of the data from SPIxSR to SPIxBUF will
not be completed and the new data will be lost. The
module will not respond to SCL transitions while
SPIROV is 1, effectively disabling the module until
SPIxBUF is read by user software.

SPI™ MODULE
Operating Function Description
Preliminary
Transmit writes are also double buffered. The user
writes to SPIxBUF. When the master or slave transfer
is completed, the contents of the shift register
(SPIxSR) is moved to the receive buffer. If any trans-
mit data has been written to the buffer register, the
contents of the transmit buffer are moved to SPIxSR.
The received data is thus placed in SPIxBUF and the
transmit data in SPIxSR is ready for the next transfer.
In Master mode, the clock is generated by prescaling
the system clock. Data is transmitted as soon as a
value is written to SPIxBUF. The interrupt is generated
at the middle of the transfer of the last bit.
In Slave mode, data is transmitted and received as
external clock pulses appear on SCK. Again, the inter-
rupt is generated when the last bit is latched. If SSx
control is enabled, then transmission and reception
are enabled only when SSx = low. The SDOx output
will be disabled in SSx mode with SSx high.
The clock provided to the module is (F
clock is then prescaled by the primary (PPRE<1:0>)
and the secondary (SPRE<2:0>) prescale factors. The
CKE bit determines whether transmit occurs on transi-
tion from active clock state to Idle clock state, or vice
versa. The CKP bit selects the Idle state (high or low)
for the clock.
16.1.1
A control bit, MODE16 (SPIxCON<10>), allows the
module to communicate in either 16-bit or 8-bit mode.
16-bit operation is identical to 8-bit operation, except
that the number of bits transmitted is 16 instead of 8.
The user software must disable the module prior to
changing the MODE16 bit. The SPI module is reset
when the MODE16 bit is changed by the user.
A basic difference between 8-bit and 16-bit operation is
that the data is transmitted out of bit 7 of the SPIxSR for
8-bit operation, and data is transmitted out of bit 15 of
the SPIxSR for 16-bit operation. In both modes, data is
shifted into bit 0 of the SPIxSR.
16.1.2
A control bit, DISSDO, is provided to the SPIxCON reg-
ister to allow the SDOx output to be disabled. This will
allow the SPI module to be connected in an input only
configuration. SDO can also be used for general
purpose I/O.
Note:
Both the transmit buffer (SPIxTXB) and
the receive buffer (SPIxRXB) are mapped
to the same register address, SPIxBUF.
