b. If = 0 (Slave Mode)
In the slave mode the TMP92CZ26A operates either in normal slave mode or in
slave mode after losing arbitration.
In the slave mode, an INTSBI interrupt request occurs when the TMP92CZ26A
receives a slave address or a GENERAL CALL from the master device, or when a
GENERAL CALL is received and data transfer is complete, or after matching
received address. In the master mode, the TMP92CZ26A operates in a slave mode
if it losing arbitration. An INTSBI interrupt request occurs when a word data
transfer terminates after losing arbitration. When an INTSBI interrupt request
occurs the is cleared to “0” and the SCL pin is pulled down to the Low-level.
Either reading/writing from/to the SBIDBR or setting the to “1” will
release the SCL pin after taking t
LOW
time.
Check the SBISR, , , and and implements processes
according to conditions listed in the next table.
Example: In case matching slave address in slave receive mode, direction bit is “1”.
