Comment
I2CDAT is configured as
Open Drain and needs a
pull-up resistor in the host
application.
According to the I
Specification Version 2.1
for the fast mode a rise
time of max. 300ns is
permitted. There is also a
maximum V
3mA specified.
The value of the pull-up
depends on the capacitive
load of the whole system
(I2C Slave + lines). The
maximum sink current of
I2CDAT and I2CCLK is
4mA.
If lines are unused keep
pins open.
Comment
If the Serial Peripheral
Interface is active the I
interface is not available.
1.083 MHz
If lines are unused keep
pins open.
