The "Port change event" interrupt of "G9006" is not the same specification as the "Input change" interrupt of "Center LSI".
When setting a "Port change event" interrupt for "Port number 0" of "Data device", an interrupt is generated even by a change
other than the least significant bit.
5.2.8
Port change interrupt flag memory
"Port change interrupt flag" can be read.
"Port change interrupt flag" is cleared by writing "1".
"Port change interrupt flag memory" has "Memory addresses" from address 0 to address 31.
The size of one "Port change interrupt flag" area is 1 byte.
The size of one "Device number" area is 4 bits.
"Memory map" is the same as "5.2.7 Port change interrupt setting memory".
The "Port change interrupt flag" area is the same position as the "Port change interrupt setting" area.
The configuration of the "Port change interrupt flag" area is the same as "Figure 5.2-1 "Port change interrupt setting" area
configuration".
5.2.9
Local LSI connection state memory
The same content as "Device-in-use" bit in "Device information area" of "Center LSI" can be read.
The connection state of "Own device" and "Virtual local LSI" is confirmed by "Request frame".
The connection state other than the "Own device" and the "Virtual local LSI" is confirmed by "Response frame".
The "Local LSI connection state" area is updated each time a "Response frame" of the "Local LSI" with the smallest "Device
number" is received.
Set "1" to the "Local LSI" bit where the "request frame" or "response frame" was confirmed.
Set "0" to the "Local LSI" bit which the "request frame" or "response frame" could not be confirmed.
The "Local LSI connection state memory" has "memory addresses" from address 0 to address 7.
The size of one "Local LSI connection state" area is 1 byte.
The size of one "device number" area is 1 bit.
