4.4.7
MRER [37]
This is an output pin for "Abnormal frame reception" signal of "Motionnet
®
".
When an abnormal frame such as a CRC error is received, "MRER = L level" is output for 3.2 μs.
Also, when an abnormal frame not addressed to "Own device" is received, "MRER = L level" is output.
Communication quality can be confirmed by counting with an external counter.
When used for LED display, "RENV1.LEDT = 1" can be set to extend the "L level" time to about 100 milliseconds.
4.4.8
MSEL [38]
This is an output pin for "Normal frame reception" signal of "Motionnet
®
".
When a normal frame is received, "MSEL = L level" is output for 3.2 μs.
When a normal frame not addressed to "Own device" is received, "MSEL = L level" is output.
4.4.9
TOUT [40]
This is an output pin for "Communication timeout" signal of "Motionnet
®
".
When the watchdog timer of "Motionnet
®
" times out, "TOUT = L level" is output.
The timeout period of the watchdog timer can be selected in "RENV1.TMD".
"TOUT" pin remains at "L level" until "Motionnet
®
" communication is resumed, so it can be used for LED display.
"Local CPU" can receive the "interrupt request" signal (INT pin) when "RENV1.QTOT = 1" is set.
4.4.10
BCST [3]
This is an output pin for "Broadcast one-shot" signal.
For details, see "6.4.3 'Broadcast one-shot' signal (BCST pin)".
4.4.11
DMOD [47]
This is an input pin that enables "Device number setting pin".
When "Reset" is executed with "DMOD = H level", "PORT2" to "PORT7" pins are changed to "Device number" (DNn) setting
pins.
At the same time, "MRER", "MSEL", and "TOUT" pins are also changed to "Virtual local LSI additional count" (RSVn) setting
pins.
