If OEMCFG5-2 = 0: 120 – 123 = 78h – 7Bh
If OEMCFG5-2 = 1: 123 – 126 = 7Bh – 7Eh
This four-byte field is for entry of the password required to access the OEM area of the MIC3003’s memory and registers. A
valid OEM password will also permit access to the user areas of memory. This field is compared to the four-byte OEMPWSET
field at serial address A6h, bytes 12 - 15 (0Ch – 0Fh). If the two fields match, access is allowed to the OEM areas of the
MIC3003 non-volatile memory at serial addresses A4h and A6h. The OEM password is set by writing the new value into
OEMPWSET. The password comparison is performed following the write to the highest address byte of OEMPW, address 7Bh
if OEMCFG5 bit 2 is low, or 7Eh if OEMCFG5 bit 2 is high. This byte must be written last.
A four-byte burst-write sequence to OEMPW may be used as this will result in the highest address byte being written last.
OEMPW is reset to zero at power on. Any values written to OEMPW will be readable by the host regardless of the
locked/unlocked status of the device. If OEMPWSET is set to zero (00000000h), the MIC3003 will remain unlocked regardless
of the contents of the OEMPW field. This is the factory default security setting.
