5.2.1 Clock Polarity (CPOL) and Phase (CPHA) control
5.2 SPI frame format
For device configured as a master in this mode, CLK and FS are forced LOW, and the
transmit data line DX is tristated whenever the SSP is idle. Once the bottom entry of the
transmit FIFO contains data, FS is pulsed HIGH for one CLK period. The value to be
transmitted is also transferred from the transmit FIFO to the serial shift register of the
transmit logic. On the next rising edge of CLK, the MSB of the 4 to 16 bit data frame is
shifted out on the DX pin. Likewise, the MSB of the received data is shifted onto the DR
pin by the off-chip serial slave device.
Both the SSP and the off-chip serial slave device then clock each data bit into their serial
shifter on the falling edge of each CLK. The received data is transferred from the serial
shifter to the receive FIFO on the first rising edge of CLK after the LSB has been latched.
The SPI interface is a four-wire interface where the SSEL signal behaves as a slave
select. The main feature of the SPI format is that the inactive state and phase of the SCK
signal are programmable through the CPOL and CPHA bits within the SSPCR0 control
register.
When the CPOL clock polarity control bit is LOW, it produces a steady state low value on
the SCK pin. If the CPOL clock polarity control bit is HIGH, a steady state high value is
placed on the CLK pin when data is not being transferred.
