IOVER
The IOVER bit is set to “1”, when the RREF pin is shorted to VSS in run mode.
The AK4160 is changed from run mode to shutdown mode for the over current
protection.
The IRQ bit setting to the edge action is fix to the active state. When the IOVER bit
is “1”, run mode is invalid. When the IOVER bit is written “1”, the IOVER bit or
IRQ2-0 bits are cleared.
D7
The IRQ bits are set to “1”, when an interrupt occurs. There are 2ways to clear
these bits. It is selected by CLRM bit in the IRQCn register.
The IRQ bits are set to the input level of IRQN2-0 terminals. Reading or writing
“1” to the IRQ bits is invalid.
The IRQ bits are set to the level of IRQN2-0 terminals. Reading or writing “1” to
the IRQ bits is invalid.
CLRM bit = “0”: When the lower byte of the IRQ Status register is read.
CLRM bit = “1”: When the related bit (IRQ2-0 bits) is written “1”, the bit is
