Bit 6—DDC Mode Switch (SW): Selects either formatless mode or the I
channel 0.
Bit 5—DDC Mode Switch Interrupt Enable Bit (IE): Enables or disables an interrupt request to
the CPU when automatic format switching is executed for IIC channel 0.
Bit 4—DDC Mode Switch Interrupt Flag (IF): Flag that indicates an interrupt request to the
CPU when automatic format switching is executed for IIC channel 0.

Description
IIC channel 0 is used with the I
[Clearing conditions]
1. When 0 is written by software
2. When a falling edge is detected on the SCL pin when SWE = 1
IIC channel 0 is used in formatless mode
[Setting condition]
When 1 is written in SW after reading SW = 0
Description
Interrupt when automatic format switching is executed is disabled
Interrupt when automatic format switching is executed is enabled
Description
No interrupt is requested when automatic format switching is executed
[Clearing condition]
When 0 is written in IF after reading IF = 1
An interrupt is requested when automatic format switching is executed
[Setting condition]
When a falling edge is detected on the SCL pin when SWE = 1
