PIC18F97J60-I/PF 64/80/100-Pin, High-Performance, 1 Mbit Flash Microcontrollers complex integrated circuits microchips

64/80/100-Pin High-Performance, 1-Mbit Flash Microcontrollers with Ethernet

  The MSSP module in I2C mode fully implements all master and slave functions (including general call support) and provides interrupts on Start and Stop bits in hardware to determine a free bus (multi-master function). The MSSP module implements the standard mode specifications, as well as 7-bit and 10-bit addressing.

Two pins are used for data transfer:

• Serial clock (SCLx) – RC3/SCK1/SCL1

(or RD6/SCK2/SCL2 for 100-pin devices)

• Serial data (SDAx) – RC4/SDI1/SDA1

(or RD5/SDI2/SDA2 for 100-pin devices)

The user must configure these pins as inputs by setting the TRISC<4:3> or TRISD<5:4> bits

The MSSP module has six registers for I2C operation. These are:

• MSSPx Control Register 1 (SSPxCON1)

• MSSPx Control Register 2 (SSPxCON2)

• MSSPx Status Register (SSPxSTAT)
