This four-byte field is the password required for access to the OEM area of the MIC3003’s memory and registers. This field is
compared to the four-byte OEMPW field at serial address A2 h . If the two fields match, access is allowed to the OEM areas of
the MIC3003 non-volatile memory at serial addresses A4 h and A6 h .
The OEM password may be set by writing the new value into OEMPWSET. The new password will not take effect until after a
power-on reset occurs or a warm reset is performed using the RST bit in OEMCFG0. This allows the new password to be
verified before it takes effect.
These registers are non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for
access to this register.
