Register Access
The SMH4046 contains a 2-wire bus interface for
register access as explained in the previous section.
This bus is highly configurable, while maintaining the
industry standard protocol. The SMH4046 responds to
one of two selectable Device Type Addresses:
1010
BIN
, generally assigned to NV-memories and the
default address for the SMH4046, or 1011
BIN
. The
Device Type Address is assigned by programming bit
3 of Register 0x0E.
Slave Address Bus Address
The configuration registers may be locked out by
setting bit 7 of register 0x0D high. This is a one-time,
non-reversible operation.
The SMH4046 has two virtual address pins, A[1:0] (set
with R0E[1:0]), associated with the 2-wire bus.
