6.8.1.2
Interrupt request mask
When "RENV1.INTM = 1" is set, the "Interrupt request" signal (INT pin) is not output.
This function is set when "INT" pin is not used with "Local CPU".
However, the "Interrupt factor" bit of "Status" (MSTS) has been changed.
Perform polling by "Local CPU" as necessary, and read the "Interrupt factor" from "Status".

6.8.2.1
Device setting change error
"G9006" can output the "Interrupt request" signal (INT pin) by the "Device setting change error" (MSTS.IAER) interrupt.
This interrupt is generated when the "Register writing" control command of the "RADD" (00h) register is written while
"MSTS.SBSY = 1" is set.
The "RADD" (00h) register is used to set the information that "G9006" connects to "Motionnet
®
".
When "MSTS.SBSY = 1" is set, the setting of this register cannot be changed.
Therefore, the "Register writing" control command to this register is ignored.
When writing the "Register writing" control command of the "RADD" (00h) register, make sure that "MSTS.SBSY = 0" is set.
6.8.2.1.1
Interrupt request output
When the "Device setting change error" interrupt occurs, "MSTS.IAER = 1" is set.
When a control command is written (after the "SS" signal rises), "INT = L level" is output.
6.8.2.1.2
Interrupt factor clear
The "Local CPU" the "Device setting change error" interrupt with the "CCAR" (20h) operation command.
When the "Device setting change error" interrupt is cleared, "MSTS.IAER = 0" is set.
When an operation command is written (after the "SS" signal rises), "INT = H level" is output.
