Only some chips allow the following:
CCS offers support for the hardware-based I2C

consult the datasheet for your target device; not all PICs support I2C
The I
remains in effect for the I2C_START, I2C_STOP, I2C_READ, I2C_WRITE and
I2C_POLL functions until another USE I2C is encountered. Software functions
are generated unless the FORCE_HW is specified. The SLAVE mode should

C library contains functions to implement an I
Sets to the master mode
Set the multi_master mode
Set the slave mode
Specifies the SCL pin (pin is a bit address)
Specifies the SDA pin
Specifies the slave mode address
Use the fast I
Sets the speed to nnnnnn hz
Use the slow I
Restart the WDT while waiting in I
Use hardware I
Use software I2C functions.
Does not allow signals to float high, signals are driven
from low to high
Bus used is not I
Associates a stream identifier with this I
identifier may then be used in functions like i
i
Do not allow clock streaching
Set an address mask for parts that support it
Instead of SCL= and SDA= this sets the pins to the first
module
Instead of SCL= and SDA= this sets the pins to the
second module

No ACK is sent until I2C_READ is called for data bytes
(slave only)
No ACK is sent until I2C_read is called for the address
byte (slave only)
Min of 300ns holdtime on SDA a from SCL goes low
