7. Group message register (GMR0: 3Ehex, GMR1: 3Fhex)
These are registers to set the group message mode.
Two messages can be set to the group message mode.
At reset, all bits are set to "0".
The group message mode is valid when the EGM0/EGM1 bit is "1".
Using GMR03 to GMR00 and GMR13 to GMR10, set the message numbers of messages that
are to be set to the group message mode.
The bit configuration is as follows:
Address MSB
3Eh
LSB
3Fh
EGM0
0
GMR03
GMR02
GMR01
GMR00
EGM1
0
GMR11
GMR12
GMR11
GMR10
GMR0
GMR1
8. Group message mask register (GMSK)
This is a register to judge identifiers when a message with a message number specified by the
group message mode GMR is received.
Using MiID28 to MiID0, set the bits to mask the identifier of a message set by the GMR bit.
Setting "1" masks the bit, setting "0" does not mask the bit.
(M0ID28 to M0ID0 are for GMR0, and M1ID28 to M1ID0 are for GMR1.)
At reset, all bits are set to "0".
The bit configuration is as follows:
Address MSB
4Eh

4Fh
