GENERAL RELEASE SPECIFICATION
PRELIMINARY
9.3.4
DDC Status Register (DSR)
This status register is readable only. All bits are cleared upon reset except bit 3 (RXAK) and
bit 1 (TXBE).
RXIF
Bit 7
The data Receive Interrupt Flag (RXIF) is set after the DDRR
is loaded with a newly received data. Once the DDRR is
loaded with received data, no more received data can be
loaded to the DDRR register. The only way to release the
DDRR register for loading next received data is that software
reads the data from the DDRR register to clear RXBF flag.
This bit is cleared by writing ’0’ to it or when the DEN is
disabled.
TXIF
Bit 6
The data Transmit Interrupt Flag is set before the data of the
DDTR register is downloaded to the shift register. It is
software’s responsibility to fill the DDTR register with new
data when this bit is set. This bit is cleared by writing ’0’ to it
or when the DEN is disabled.
MATCH
Bit 5
The MATCH flag is set when the received data in the DDRR
register is an calling address which matches with the address
or its extended addresses (EXTAD=1) specified in the DADR
register.
SRW
Bit 4
The Slave RW bit will indicate the data direction of DDC
protocol. It is updated after the calling address is received in
the DDC2 protocol. When it is one, the master will read the
data from DDC module, so the module is in transmit mode.
When it is zero, the master will send data to the DDC module,
the module is in receive mode. When DDC1EN is set, the
SRW bit will be one. The reset state of it is zero.
RXAK
Bit 3
If the received acknowledge bit (RXAK) is low, it indicates an
acknowledge signal has been received after the completion of
8 data bits transmission on the bus. If RXAK is high, it
indicates no acknowledge signal has been detected at the 9th
clock. Then the module will release the SDA line for the
master to generate ’stop’ or ’repeated start’ condition. It is set
upon reset.
SCLIF
Bit 2
This SCLIF flag is set by the falling edge of SCL line only
when DDC1EN is enabled. This bit is cleared by writing zero
to it, clearing DDC1EN bit or when the DEN is disable.
