Sougata,

I think my SSPCON register is already set but, just to make sure, am I right to say that in the PIC's datasheet, the register settings have default values I can read like here "R/W-0" and it would mean that the bit is set to 0?

Code:
REGISTER 10-2: SSPCON: SYNCHRONOUS SERIAL PORT CONTROL REGISTER (ADDRESS 14h)
R/W-0 R/W-0 R/W-0   R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
WCOL  SSPOV SSPEN(1)CKP   SSPM3 SSPM2 SSPM1 SSPM0
bit 7                                       bit 0
