PIC32MX3XX/4XX
17.2
The PIC32MX3XX/4XX SPI module operates in normal
Master or Slave modes and offers the following addi-
tional modes:
• Framed Master
• Framed Slave
• 8, 16, 32-Bit Data Width Transfers
• Slave Select (Slave mode only)
Below is a typical system Master – Slave connection
diagram.
17.2.1
The PIC32MX3XX/4XX SPI module allows three types
of data widths when transmitting and receiving data
over an SPI bus. The selection of data width deter-
mines the minimum length of SPI data.

Note 1: Using the SSx pin in Slave mode of operation is optional.

2: User must write transmit data to SPIxBUF and read received data from SPIxBUF. The SPIxTXB and SPIxRXB
8, 16, 32-BIT OPERATION
registers are memory mapped to SPIxBUF.

Preliminary
Serial Clock
.
Two
(SPIxCON<11:10>), define the mode of operation. To
change the mode of operation on the fly, the SPI mod-
ule must be idle, i.e., not performing any transactions.
If the SPI module is switched off (SPIxCON<15> = 0),
the new mode will be available when the module is
again switched on.
The number of clock pulses at the SCKx pin are depen-
dent on the selected mode of operation. For 8-Bit mode,
8 clocks; for 16-Bit mode, 16 clocks; and for 32-Bit
mode, 32 clocks are required.
