An interrupt is generated at the falling of the 9th clock during address transfer independently of the setting of this bit.
The setting of this bit is valid when the address transfer is completed. When in master mode, a wait is inserted at the
falling edge of the ninth clock during address transfers. For a slave device that has received a local address, a wait is
inserted at the falling edge of the ninth clock after ACK is issued. However, when the slave device has received an
extension code, a wait is inserted at the falling edge of the eighth clock.
Condition for clearing (WTIM0 bit = 0)
• Cleared by instruction
• Reset
The ACKE0 bit setting is invalid for address reception. In this case, ACK is generated when the addresses match.
However, the ACKE0 bit setting is valid for address reception of the extension code.

Interrupt request is generated at the eighth clock’s falling edge.
Master mode: After output of eight clocks, clock output is set to low level and wait is set.
Slave mode: After input of eight clocks, the clock is set to low level and wait is set for master device.
Interrupt request is generated at the ninth clock’s falling edge.
Master mode: After output of nine clocks, clock output is set to low level and wait is set.
Slave mode: After input of nine clocks, the clock is set to low level and wait is set for master device.
Disable acknowledgment.
Enable acknowledgment. During the ninth clock period, the SDA line is set to low level.
Do not cancel wait
Cancel wait. This setting is automatically cleared to 0 after wait is canceled.
Enable/disable generation of interrupt request when stop condition is detected
Control of wait and interrupt request generation
