address other than that of the local address is received, ACK is not generated (NACK).

When the local address is received, ACK is automatically generated, regardless of the value of ACKE0. When an
When an extension code is received, ACK is generated if ACKE0 is set to 1 in advance.
How ACK is generated when data is received differs as follows depending on the setting of the wait timing.
• When 8-clock wait state is selected (bit 3 (WTIM0) of IICC0 register = 0):
• When 9-clock wait state is selected (bit 3 (WTIM0) of IICC0 register = 1):
By setting ACKE0 to 1 before releasing the wait state, ACK is generated at the falling edge of the eighth clock of
the SCL0 pin.
ACK is generated by setting ACKE0 to 1 in advance.
