15.2.6
In Slave mode, the data is transmitted and received as
external clock pulses appear on SCK. When the last bit
is latched, the SSPIF interrupt flag bit is set.
Before enabling the module in SPI Slave mode, the clock
line must match the proper Idle state. The clock line can
be observed by reading the SCK pin. The Idle state is
determined by the CKP bit of the SSPCON1 register.
While in Slave mode, the external clock is supplied by
the external clock source on the SCK pin. This external
clock must meet the minimum high and low times as
specified in the electrical specifications.
While in Sleep mode, the slave can transmit/receive
data. When a byte is received, the device will wake-up
from Sleep.

15.2.7
The SS pin allows a Synchronous Slave mode. The
SPI must be in Slave mode with SS pin control enabled
(SSPCON1<3:0> = 0100). When the SS pin is low,
transmission and reception are enabled and the SDO
pin is driven. When the SS pin goes high, the SDO pin
is no longer driven, even if in the middle of a transmitted
byte and becomes a floating output. External
pull-up/pull-down resistors may be desirable depend-
ing on the application.
When the SPI module resets, the bit counter is forced
to ‘0’. This can be done by either forcing the SS pin to
a high level or clearing the SSPEN bit.
