The interrupt request of the IIC contains 6 types when the I
clock synchronous serial format is used. Table 15.3 lists the Interrupt Request of IIC.
Since these interrupt requests are allocated at the IIC interrupt vector table, determining the factor by
each bit is necessary.
When the generation conditions on the Table 15.3 are met, the IIC interrupt request is generated. Set the
interrupt generation conditions to “0” by the IIC interrupt routine. However, the TDRE and TEND bits are
automatically set to “0” by writing transmit data to the ICDRT register and the RDRF bit is automatically
set to “0” by reading the ICDRR register. When writing transmit data to the ICDRT register, the TDRE bit
is set to “0”. When data is transferred from the ICDRT to ICDRS registers, the TDRE bit is set to “1” and
when further setting the TDRE bit to “0”, extra 1 byte may be transmitted.
