I

C SERIAL COMMUNICATION — SIO1
The I
2
C serial port is identical to the I
2
C serial port on the 8XC552,
8XC654, and 8XC652 devices. The operation of this subsystem is
described in detail in the 8XC552 section of this manual.
Note that in both the P89C668 and the 8XC552 the I
2
C pins are
alternate functions to port pins P1.6 and P1.7. Because of this,
P1.6 and P1.7 on these parts do not have a pull-up structure as
found on the 80C51. Therefore P1.6 and P1.7 have open drain
outputs on the P89C668.

NOTES:
1. These frequencies exceed the upper limit of 100 kHz of the I
2
C-bus specification and cannot be used in an I
2
C-bus application.
2. At f
OSC
= 12 MHz/15 MHz the maximum I
2
C bus rate of 100 kHz cannot be realized due to the fixed divider rates.
