TMP92CM22 receives a slave address or a GENERAL CALL from the master
device, or when a GENERAL CALL is received and data transfer is completed, or
after matching received address. In the master mode, the TMP92CM22 operates
in a slave mode if it losing arbitration. An INTSBE0 interrupt request is
generated when a word data transfer terminates after losing arbitration. When an
INTSBE0 interrupt request is generated the <PIN> is cleared to "0" and the SCL
pin is pulled down to the low level. Either reading/writing from/to the SBI0DBR or
setting the <PIN> to "1" will release the SCL pin after taking t
processes according to conditions listed in the next table.

Conditions
Set the number of bits of single word to
<BC2:0>, and write the transmit data to
SBI0DBR.
Check the <LRB>, If <LRB> is set to "1",
set <PIN> to "1", reset "0" to <TRX> and
release the bus for the receiver no
request next data. If <LRB> was cleared
to "0", set bit number of single word to
<BC2:0> and write the transmit data to
SBI0DBR for the receiver requests next
data.
Read the SBI0DBR for setting the <PIN>
to "1" (Reading dummy data) or set the
<PIN> to "1".
