Conditions

Process

The TMP88CU74 loses arbitration when

transmitting a slave address and receives a slave

address of which the value of the direction bit sent

from another master is “1”.

In the slave receiver mode, the TMP88CU74

receives a slave address of which the value of the

direction bit sent from the master is “1”.

Set the number of bits in 1 word to the

BC and write transmitted data to the

SBIDBR.

In the slave transmitter mode, 1-word data is

transmitted.

Check the LRB. If the LRB is set to

“1”, set the PIN to “1” since the

receiver does not request next data.

Then, clear the TRX to “0” release the

bus. If the LRB is cleared to “0”, set

the number of bits in a word to the BC

and write transmitted data to the

SBIDBR since the receiver requests

next data.

1/0

The TMP88CU74 loses arbitration when

transmitting a slave address and receives a slave

address or GENERAL CALL of which the value of

the direction bit sent from another master is “0”.

The TMP88CU74 loses arbitration when

transmitting a slave address or data and terminates

transferring word data.

1/0

In the slave receiver mode, the TMP88CU74

receives a slave address or GENERAL CALL of

which the value of the direction bit sent from the

master is “0”.

Read the SBIDBR for setting the PIN

to “1” (reading dummy data) or write

“1” to the PIN.

1/0

In the slave receiver mode, the TMP88CU74

terminates receiving of 1-word data.

Set the number of bits in a word to the

BC and read received data from the

SBIDBR.

(4) Stop condition generation

When the BB is “1”, a sequence of generating a stop condition is started by writing

“1” to the MST, TRX, and PIN, and “0” to the BB. Do not modify the contents of the

MST, TRX, BB, PIN until a stop condition is generated on a bus.
