T0IFR
When T0 interrupt occurs, this bit becomes ‘1’. For clearing bit, write ‘0’ to this bit or
auto clear by INT_ACK signal. Writing “1” has no effect.
0
T0 interrupt no generation
1
T0 interrupt generation
IICIFR
This is an interrupt flag bit. When an interrupt occurs, this bit becomes ‘1’. This bit is
cleared when all interrupt source bits in the I2CSR register are cleared to “0b”. Writing
“1” has no effect.

I2C interrupt no generation
1
I2C interrupt generation
EIFLAG[4:0]
When an external interrupt (EINT0/1/10/11/12) is occurred, the flag becomes ‘1’. The
flag is cleared by writing a ‘0’ to the bit or automatically cleared by INT_ACK signal.
Writing “1” has no effect.
