C INTERFACE
The serial port supports the twin line I
2
C-bus, con-
sisting of a data line (SDA1), and a clock line
(SCL1) as shown in Figure 38. Depending on the
configuration, the SDA1 and SCL1 lines may re-
quire pull-up resistors.
These lines also function as I/O port lines if the I
2
C
bus is not enabled.
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.

These functions are controlled by the SFRs (see
Tables 50, 51, and Table 52, page 75):
–
S2CON: the control of byte handling and the
operation of 4 mode.
–
S2STA: the contents of its register may also
be used as a vector to various service
routines.
–
S2DAT: data shift register.
–
S2ADR: slave address register. Slave
address recognition is performed by On-Chip
H/W.
