The SPI module has flexible operating modes, which are discussed in the following sections:
• 8-bit and 16-bit Data Transmission/Reception
• Master and Slave Modes
• Framed SPI Modes
• SPI1 Receive-only Operation
• SPI1 Error Handling
The MODE16 control bit (SPI1CON1<10>) allows the module to communicate in either 8-bit or
16-bit mode. The functionality will be the same for each mode, except for the number of bits that
are received and transmitted. Additionally, the following items should be noted in this context:
• The module is reset when the value of the MODE16 bit is changed. Consequently, the bit
• Data is transmitted out of bit 7 of the SPI1SR register for 8-bit operation, while it is transmit-
• When transmitting or receiving data, 8 clock pulses at the SCK1 pin are required to shift
Data can be thought of as taking a direct path between the Most Significant bit (MSb) of one
module’s shift register and the Least Significant bit (LSb) of the other, and then into the
appropriate Transmit or Receive Buffer. The module configured as the master module provides
the serial clock and synchronization signals (as required) to the slave device. Figure 35-2 shows
the connection of the Master and Slave modules.
