FIGURE 1 – ISA INTERFACE ACCESS
I
2C Interface
The second interface uses the I
2C Serial Bus.
The
MON35W42
uses
three
serial
bus
addresses. The first address defined at CR[48h]
can read/write all registers excluding Bank 1 and
Bank 2 temperature sensor 2/3 registers. The
second address defined at CR[4Ah] bit2-0 can
only be used to read/write temperature sensor 2
registers, and the third address defined at
