Function
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.

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.
