PIC16F87X
9.2.15
Clock arbitration occurs when the master, during any
receive, transmit, or Repeated START/STOP condi-
tion, de-asserts the SCL pin (SCL allowed to float high).
When the SCL pin is allowed to float high, the baud rate
generator (BRG) is suspended from counting until the
SCL pin is actually sampled high. When the SCL pin is
sampled high, the baud rate generator is reloaded with
the contents of SSPADD<6:0> and begins counting.
This ensures that the SCL high time will always be at
least one BRG rollover count in the event that the clock
is held low by an external device (Figure 9-18).

While in SLEEP mode, the I
addresses or data, and when an address match or
complete byte transfer occurs, wake the processor
from SLEEP (if the SSP interrupt is enabled).

A RESET disables the SSP module and terminates the
current transfer.
