Write: IICC2
— to enable or disable general call
— to select 10-bit or 7-bit addressing mode
Write: IICA
— to set the slave address
Write: IICC1
— to enable IIC and interrupts
Initialize RAM variables (IICEN = 1 and IICIE = 1) for transmit data
Initialize RAM variables used to achieve the routine shown in
Write: IICF
— to set the IIC baud rate (example provided in this chapter)
Write: IICC1
— to enable IIC and interrupts
Initialize RAM variables (IICEN = 1 and IICIE = 1) for transmit data
Initialize RAM variables used to achieve the routine shown in
Write: IICC1
— to enable TX
Write: IICC1
— to enable MST (master mode)
Write: IICD
— with the address of the target slave. (The lsb of this byte determines whether the communication is
The routine shown in
incoming IIC message that contains the proper address begins IIC communication. For master operation,
communication must be initiated by writing to the IICD register.
