The PIC16F1827 has two MSSP modules, MSSP1 and
MSSP2, each module operating independently from
the other.

module, it is very important to pay close
attention to SSPxCONx register names.
SSP1CON1 and SSP1CON2 registers
control different operational aspects of the
same module, while SSP1CON1 and
SSP2CON1 control the same features for
two different modules.
ences to an MSSP module in any of its
operating modes may be interpreted as
being equally applicable to MSSP1 or
MSSP2. Register names, module I/O sig-
nals, and bit names may use the generic
designator ‘x’ to indicate the use of a
numeral to distinguish a particular module
when required.
