Register Allocation
The EMC1002 can be set to standby mode (low power) by setting a bit in the Configuration Register
as described in

Note 4.5
At device power-up, the default values are stored in registers as shown. A power-on-reset is initiated
when power is first applied to the part and the V
undefined registers will return 00h and writes to undefined registers will be ignored.
The EMC1002 uses an interlock mechanism that locks the low byte value when the high byte register
is read. This prevents updates to the low byte register between high byte and low byte reads. This
