slave select. The main feature of the SPI format is that the operation timing of
SP0CLK is programmable through the <SPO> and <SPH> bits in the SSP0CR0 control
register.
SSP0CR0<SPO>
SSP0CR0<SPH>
SPI operation examples:
2) SPI
SP0FSS
SP0CLK
SSP0CR0<SPO> specifies the SP0CLK level during idle periods.
<SPO> = 1: SP0CLK is held High.
<SPO> = 0: SP0CLK is held Low.
SSP0CR0<SPH> selects the clock edge for latching data.
SSP0CR0<SPH> = 0: Data is latched on the first clock edge.
SSP0CR0<SPH> = 1: Data is latched on the second clock edge.
SPI (single transfer, <SPO> = 0 & <SPH> = 0)
SP0DO
The SPI interface is a four-wire interface where the SP0FSS signal behaves as a
