19.0
The Master Synchronous Serial Port (MSSP) module is
a serial interface, useful for communicating with other
peripheral or microcontroller devices. These peripheral
devices include serial EEPROMs, shift registers,
display drivers and A/D Converters.
19.1
The MSSP module can operate in one of two modes:
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I
The I
hardware:
• Master mode
• Multi-Master mode
• Slave mode with 5-bit and 7-bit address masking
All members of the PIC18F46J11 family have two
MSSP modules, designated as MSSP1 and MSSP2.
The modules operate independently:
• PIC18F4XJ11 devices – Both modules can be
• PIC18F2XJ11 devices:

PIC18F46J11 FAMILY
All of the MSSP1 module-related SPI and I
functions are hard-mapped to specific I/O pins.
For MSSP2 functions:
• SPI I/O functions (SDO2, SDI2, SCK2 and SS2)
• I
On all PIC18F46J11 family devices, the SPI DMA capa-
bility can only be used in conjunction with MSSP2. The
SPI DMA feature is described in

(PPS) module.
These functions may be configured to use any of
the RPn remappable pins, as described in
