Enable/disable timeout function

logic 0 = disable

logic 1 = enable

The least significant bit of I2CTO (TE bit) is used as a timeout enable/disable. A logic 1

will enable the timeout function.

The timeout can be computed by the following equation:

Decimal value for I2CClock is from Section 6.2.4 "I2C-bus clock rates register (I2CClk)"

The timeout value is an approximate value.

In the case of arbitration loss, SC18IS604 transmits a START condition when the bus

becomes free unless the timeout condition is reached. If the timeout condition is reached,

I2CStat.
