TOE (Timeout detect function enable bit) (b0)
The TOE bit enables the timeout detect function. Refer to 25.3.9 "Timeout Detection" for details.
TOF (Timeout detect flag) (b1)
The TOF bit is enabled when the TOE bit is set to 1. When the TOF bit becomes 1 (detected), the IR bit
in the IICIC register becomes 1 (interrupt requested) at the same time.
Conditions to become 0:
•
The ES0 bit in the S1D0 register is set to 0 (I
•
The IHR bit in the S1D0 register is set to 1 (I
