C Clock

The I C module uses the internal clock output by the 16-bit timer Ch.2 as the synchronizing clock. This clock is

output from the SCL pin to the slave device while also driving the shift register. The clock should be programmed
to output a signal matching the transfer rate from the 16-bit timer Ch.2. For more information on 16-bit timer con-
trol, refer to "11 16-bit Timer (T16)."
The I 2 C module does not function as a slave device. The SCL input pin is used to check the I 2 C bus SCL signal sta-
tus. It is not used for synchronization clock input.
