Bit no.
3 and 2 RBS1
(9) DLCR8 to DLCR13: Node ID Registers
DLCR8 to DLCR13 store the node ID of the self office. After comparing the destination addresses in the receive
packet with the values of the node ID registers, the matching packets are received according to the setting
conditions of the Address Match Mode bits of DLCR5.
Usually, set bit 0 (ID 0) of DLCR8 to 0 (When bit 0 of the destination address is 1, the received data serve as
the multicast address and the packet is received according to the setting conditions of the Address Match Mode
bits of DLCR5, irrespective of their values).
The initial values of the node ID registers are undefined. Reading and writing are possible only when bit 7 (ENA
DLC) of DLCR6 is 1.

RBS0
The MB86967 has three internal register sets. Bank switching
by these bits allows the system to access each register set.
DLCR0 to DLCR7 can always be accessed irrespective of the
conditions of register banks.

When the system bus is the 16-bit
mode, byte swapping is not
performed for access to BMPR8.
The bus is an Intel 16-bit bus.
When the system bus is the 16-bit
mode, byte swapping is performed
for access to BMPR8, switching
between upper and lower data. The
bus is a Motorola 16-bit bus.
