9.2.3 SLEEP OPERATION
While in SLEEP mode, the I²C module can receive
addresses or data. When an address match or com-
plete byte transfer occurs, wake the processor from
SLEEP (if the SSP interrupt is enabled).
9.2.4 EFFECTS OF A RESET
A RESET disables the SSP module and terminates the
current transfer.
