Slave Operation
In slave mode, the data is transmitted and received as the external clock pulses appear on SCK.
When the last bit is latched, the interrupt flag bit SSPIF is set.
The clock polarity is selected by appropriately programming bit CKP (SSPCON<4>). This then
would give waveforms for SPI communication as shown in
Figure 15-5
the minimum high and low times.
In sleep mode, the slave can transmit and receive data. When a byte is received, the device will
wake-up from sleep, if the interrupt is enabled.
