6.2.5 I2C-bus time-out register (I2CTO)
The time-out register is used to determine the maximum time that the I2C-bus master is
allowed to complete a transfer before setting an I2C-bus time-out interrupt.
The least signicant bit of I2CTO (TE bit) is used as a time-out enable/disable. A logic 1
will enable the time-out function.
On the SC18IS600 the time-out oscillator operates at 57.6 kHz. For the SC18IS601 the
time-out oscillator frequency can be determined using Equation 3:
(3)
This oscillator is fed into a 16-bit down counter. The down counter’s lower nine bits are
loaded with ‘1’, while the upper seven bits are loaded with the contents of I2CTO.
The time-out value is an approximate value.
In the case of arbitration loss, the SC18IS600/601 will transmit a START condition when
the bus becomes free unless the time-out condition is reached. If the time-out condition is
reached, an interrupt will be generated on the INT pin. The ‘I2C-bus time-out’ status can
be read in I2CStat.
