C INTERFACE
There are two serial I
2
C ports implemented in the
uPSD325X devices.
The serial port supports the twin line I
2
C-bus, con-
sists of a data line (SDAx) and a clock line (SCLx).
Depending on the configuration, the SDA and SCL
lines may require pull-up resistors.
I
SDA1, SCL1: the serial port line for DDC
Protocol
I
SDA2, SCL2: the serial port line for general I

C
bus connection
In both I
2
C interfaces, these lines also function as
I/O port lines as follows.
I
SDA1 / P4.0, SCL1 / P4.1, SDA2 / P3.6, SCL2 /
P3.7
The system is unique because data transport,
clock generation, address recognition and bus
control arbitration are all controlled by hardware.
The I
2
C serial I/O has complete autonomy in byte
handling and operates in 4 modes.
I
Master transmitter
I
Master receiver
I
Slave transmitter
I
Slave receiver
These functions are controlled by the SFRs.
I
SxCON: the control of byte handling and the
operation of 4 mode.
I
SxSTA: the contents of its register may also be
used as a vector to various service routines.
I
SxDAT: data shift register.
I
SxADR: slave address register. Slave address
recognition is performed by On-Chip H/W.
