Notes 1. The signal of this bit is invalid while the IICE0 bit is 0. Set this bit during that period.
If the WUP bit of the IICA control register 1 (IICACTL1) is 1, no stop condition interrupt will be generated even if
SPIE0 = 1.
Condition for clearing (SPIE0 = 0)
• Cleared by instruction
• Reset
An interrupt is generated at the falling edge of the ninth 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 an acknowledge (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 = 0)
• Cleared by instruction
• Reset
Condition for clearing (ACKE0 = 0)

2. The set value is invalid during address transfer and if the code is not an extension code.
When the device serves as a slave and the addresses match, an acknowledgment is generated
regardless of the set value.

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 SDAA0 line is set to low level.
