Default Value
Serial Address
Byte Address
USER passwords are entered in this field. This field is compared to the USRPWSET field at serial address A2h, byte 250. If the
two fields match, access is allowed to the USER areas of the MIC3001 non-volatile memory at serial addresses A0h and A2h. If
a valid USER password has not been entered, writes to the serial ID fields and user scratchpad areas of A0h and A2h will not be
allowed and USRPWSET will be unreadable (returns all zeroes).
Default Value
Serial Address
Byte Address
The lower seven bits of this register contain the most-significant bits of the 15-bit power-on hours measurement. POHFLT is an
error flag. The value in this register should be combined with the Power-on Hours, Low Byte, POHl, to yield the complete result.
If POHFLT is set, the power-on hour meter data has been corrupted and should be ignored. It is recommended that a two-byte
(or more) sequential read operation be performed on POHh and POHl to insure coherency between the two registers. This
register is non-volatile and will be maintained through power and reset cycle.

Default Value
Serial Address
Byte Address
This register contains the least-significant eight bits of the 15-bit power-on hours measurement. The value in this register should
be combined with the Power-on Hours, High Byte, POHh, to yield the complete result. If POHFLT is set, the power-on hour
meter data has been corrupted and should be ignored. It is recommended that a two-byte (or more) sequential read operation
be performed on POHh and POHl to insure coherency between the two registers. This register is non-volatile and will be
maintained through power and reset cycles.
