MSM6636/6636B User’s Manual
Internal Register Details
3 – 10
LAN BUS output disable (PB0, NB0)
When an abnormality occurs on LAN BUS, its output (external driving) can be disabled.
(PB0) 0: LAN BUS(+) output is enabled. However, when an abnormality is detected on LAN BUS(+), it is
automatically disabled and when it becomes bus idle status, it is automatically enabled.
1: LAN BUS(+) output is disabled regardless of the detection of LAN BUS(+) abnormality. It is
recommended that this setting be made after checking that interrupt request flags BPG and BPV are
set. With PB0 set to “1”, the interrupt request flag BPG is always set during message transmission.
(NB0) 0: LAN BUS(–) output is enabled. However, when an abnormality is detected on LAN BUS(–), it is
automatically disabled and when it becomes bus idle status, it is automatically enabled.
1: LAN BUS(–) output is disabled regardless of the detection of LAN BUS(–) abnormality. It is
recommended that this setting be made after checking that interrupt request flags BNG and BNV are
set. With NB0 set to “1”, the interrupt request flag BNV is always set during message transmission.

In the case of communication by functional addressing, 15 types of address values in the above register are
automatically filtered in sequence.
Even if 15 types are not used for functional addressing, all 15 bytes are filtered. Therefore set the functional
address value in all address areas from the host CPU during initial setting.
(For example, write the same functional address value in unnecessary address areas.)
