SM8213AM

NIPPON PRECISION CIRCUITS—23

Address Set Flags

In the SM8213AM, each of the 8 independent

addresses can be assigned a frame.

Address settings are made in 8 batches in write mode

immediately after power is applied and immediately

after reset (9 batches total, including the parameter

batch). All batches should be set. If not all batches

are set, subsequent operation may become unstable.

Also, an address setting can be modiﬁed during nor-

mal operation, 1 address at a time, with no adverse

effects.

Ensure that there are not multiple writes requests to

turn ON the same address.

Bits 1 to 7

These bits form the address set command.

Bit 8

These bits are the address (bits 9 to 32) enable ﬂags.

When 1, the address set by bits 9 to 32 are valid.

When 0, the address set by bits 9 to 32 are invalid.

Bits 9 to 11

These bits are the address (bits 15 to 32) call sign set

ﬂags.

Using 8-address control, the call signs are A, B, C,

D, E, F, G and H.

Bits 12 to 14

These bits are the address (bits 15 to 32) frame

assign ﬂags.

Any frame can be assigned individually to any of the

8 controllable addresses. Up to 8 frames can be

assigned.

Bits 15 to 32

Address bits.

The 18-bit address should be written with MSB ﬁrst.
