Description
DDC Mode Switch Enable
0: Disables automatic switching of IIC channel 0 from
1: Enables automatic switching of IIC channel 0 from
DDC Mode Switch
0: Uses IIC channel 0 with the I
1: Uses IIC channel 0 in formatless mode
[Setting condition]
When 1 is written in SW after reading SW = 0
[Clearing conditions]
DDC Mode Switch Interrupt Enable Bit
0: Disables interrupts when automatic format switching is
1: Enables interrupts when automatic format switching is
DDC Mode Switch Interrupt Flag
Indicates an interrupt request to the CPU is generated
when automatic format switching is executed for IIC_0.
[Setting condition]
