EQUATION 17-1:
SERIAL CLOCK RATE
17.12.4
CLOCK ARBITRATION
Clock arbitration occurs when the master deasserts the
SCL pin (SCL allowed to float high) during any receive,
transmit, or Restart/Stop condition. When the SCL pin
is allowed to float high, the Baud Rate Generator is
suspended from counting until the SCL pin is actually
sampled high. When the SCL pin is sampled high, the
Baud Rate Generator is reloaded with the contents of
I2CBRG and begins counting. This ensures that the
SCL high time will always be at least one BRG rollover
count in the event that the clock is held low by an exter-
nal device.
17.12.5
MULTI-MASTER COMMUNICATION,
BUS COLLISION AND BUS
ARBITRATION
Multi-Master operation support is achieved by bus arbi-
tration. When the master outputs address/data bits
onto the SDA pin, arbitration takes place when the
master outputs a ‘1’ on SDA, by letting SDA float high
while another master asserts a ‘0’. When the SCL pin
floats high, data should be stable. If the expected data
on SDA is a 1 and the data sampled on the SDA
pin = 0, then a bus collision has taken place. The mas-
ter sets the MI2CIF pulse and resets the master portion
of the I2C port to its Idle state.
If a transmit was in progress when the bus collision
occurred, the transmission is halted, the TBF flag is
cleared, the SDA and SCL lines are deasserted, and a
value can now be written to I2CTRN. When the user
services the I2C master event Interrupt Service Rou-
tine, if the I2C bus is free (i.e., the P bit is set) the user
can resume communication by asserting a Start
condition.
If a Start, Restart, Stop or Acknowledge condition was
in progress when the bus collision occurred, the condi-
tion is aborted, the SDA and SCL lines are deasserted,
and the respective control bits in the I2CCON register
are cleared to 0. When the user services the bus colli-
sion Interrupt Service Routine, and if the I2C bus is free,
the user can resume communication by asserting a
Start condition.
The Master continues to monitor the SDA and SCL
pins, and if a Stop condition occurs, the MI2CIF bit is
set.
A write to the I2CTRN starts the transmission of data at
the first data bit, regardless of where the transmitter left
off when bus collision occurred.
In a Multi-Master environment, the interrupt generation
on the detection of Start and Stop conditions allows the
determination of when the bus is free. Control of the I2C
bus can be taken when the P bit is set in the I2CSTAT
register, or the bus is Idle and the S and P bits are
cleared.
17.13 I2C Module Operation During CPU
Sleep and Idle Modes
17.13.1
I2C OPERATION DURING CPU
SLEEP MODE
When the device enters Sleep mode, all clock sources
to the module are shutdown and stay at logic ‘0’. If
Sleep occurs in the middle of a transmission, and the
state machine is partially into a transmission as the
clocks stop, the transmission is aborted. Similarly, if
Sleep occurs in the middle of a reception, the reception
is aborted.
17.13.2
I2C OPERATION DURING CPU IDLE
MODE
For the I2C, the I2CSIDL bit selects if the module stops
or continues on Idle. If I2CSIDL = 0, the module contin-
ues operation on assertion of the Idle mode. If I2CSIDL
= 1, the module stops on Idle.
