Slave Operation

SDI
In slave mode, the data is transmitted and received as the external clock pulses appear on SCK.
When the last bit is latched the SSPIF interrupt flag bit is set.
The clock polarity is selected by appropriately programming the CKP bit (SSPCON<4>). This
then would give waveforms for SPI communication as shown in
where the MSb is transmitted first. When in slave mode the external clock must meet the mini-
mum high and low times.
In sleep mode, the slave can transmit and receive data and wake the device from sleep if the
interrupt is enabled.
