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.

Legend: x = unknown, u = unchanged, r= reserved, - = unimplemented read as ’0’. Shaded cells are not used by the SSP in I2C
mode.
Note 1: These bits are reserved; always maintain these bits clear.
