When using the "Port change interrupt information reading" control command, set "RENV1.QPOV = 1" to generate a "Port
change interrupt information acquisition failure event" (MSTS.IPOV) interrupt.
For details on the "Port change interrupt information acquisition failure event" (MSTS.IPOV) interrupt, see "6.8.2.7 Port change
interrupt information acquisition failure event".

Local LSI connection state reading
"Read-out data" can be input from a "Local LSI connection state memory" by specifying the "Memory address".

Data
(7:0)
The "ss" bit is the "Slave number" (SN) bit of the "Control command".
The "Memory address" is from "0" to "7".
When the "Read-out data" is 2 bytes or more, the "Read-out data" is input while incrementing the "Memory address".
When the "Memory address" is incremented from "7", it becomes "0".
The "Read-out data" can be input unlimitedly in 1-byte units.
For example, when inputting "Read-out data" that from "Device number 0" (DN0) to "Device number 15" (DN15), output the
following data:

This is the data when the "ss" bit is "00".
