ST92163 - I2C BUS INTERFACE
I
2
C INTERFACE
(Cont’d)
– Address byte successfully transmitted in Mas-
ter mode.
(I2CSR1.EVF = 1 and I2CSR2.ADDTX=1)
Bit 6 =
ADD10
10-bit addressing in Master mode.
This bit is set when the master has sent the first
byte in 10-bit address mode. Aninterrupt is gener-
ated if ITE=1.
It is cleared by software reading I2CSR1 register
followed by a write in the I2CDR register of the
second address byte. It is also cleared by hard-
ware when peripheral is disabled (I2CCR.PE=0)
or when the STOPF bit is set.
0: No ADD10 event occurred.
1: Master has sent first address byte (header).
Bit 5 =
TRA
Transmitter/ Receiver.
When BTF flag of this register is set and also
TRA=1, thena data bytehas to be transmitted. It is
cleared automatically when BTF is cleared. It is
also cleared by hardware after the STOPF flag of
I2CSR2 register is set, loss of bus arbitration
(ARLO flag of I2CSR2 register is set) or when the
interface is disabled (I2CCR.PE=0).
0: A data byte is received (if I2CSR1.BTF=1)
1: A data byte can be transmitted (if
I2CSR1.BTF=1)
Bit 4 =
BUSY
Bus Busy.
It indicates a communication in progress on the
bus. The detection of the communications is al-
ways active (even if the peripheral is disabled).
This bit is set by hardware on detection of a Start
condition and cleared by hardware on detection of
a Stop condition. This information is still updated
when the interface is disabled (I2CCR.PE=0).
0: No communication on the bus
1: Communication ongoing on the bus
Bit 3 =
BTF
Byte Transfer Finished.
This bit is set by hardware as soon as a byte is cor-
rectly received orbefore thetransmission of a data
byte with interrupt generation if ITE=1. It is cleared
by software reading I2CSR1 registerfollowed by a
read or write of I2CDR register or when DMA is
complete. It is also cleared by hardware when the
interface is disabled (I2CCR.PE=0).
– Followinga byte transmission, this bit is set after
reception ofthe acknowledgeclock pulse.BTFis
cleared by reading I2CSR1 register followed by
writing the next byte in I2CDR register or when
DMA is complete.
– Following a byte reception, this bit is set after
transmission of the acknowledge clock pulse if
ACK=1. BTF is cleared by reading I2CSR1 reg-
ister followed by reading the byte from I2CDR
register or when DMA is complete.
The SCL line is held low while I2CSR1.BTF=1.
0: Byte transfer not done
1: Byte transfer succeeded
Bit 2 =
ADSL
Address matched (Slave mode).
This bit is set by hardware if thereceived slave ad-
dress matches the I2COAR1/I2COAR2 register
content or a General Call address. An interrupt is
generated if ITE=1. It is cleared by software
reading I2CSR1 register or by hardware when the
interface is disabled (I2CCR.PE=0). The SCL line
is held low while ADSL=1.
0: Address mismatched or not received
1: Received address matched
Bit 1 =
M/SL
Master/Slave.
This bitis set by hardware as soon as the interface
is in Master mode (Start condition generated on
the lines after the I2CCR.START bit is set). It is
cleared by hardware after detecting a Stop condi-
tion on the bus or a loss of arbitration (ARLO=1). It
is also cleared when the interface is disabled
(I2CCR.PE=0).
0: Slave mode
1: Master mode
Bit 0 =
SB
Start Bit (Master mode).
This bit is set by hardware as soon as the Start
condition is generated (following a write of
START=1 if the bus is free). An interrupt is gener-
ated if ITE=1. It is cleared by software reading
I2CSR1 register followed by writing the address
byte in I2CDR register. It is also cleared by hard-
ware
when
the
interface
(I2CCR.PE=0).
The SCL line is held low while SB=1.
0: No Start condition
1: Start condition generated
is
disabled
