The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV001TC/BC are erased or programmed in a system without access to high voltage on the A
command sequence is illustrated in Table 6. (Refer to Autoselect Command section.)
Byte 0 (A
code (MBM29LV001TC = EDH and MBM29LV001BC = 6DH). These two bytes/words are given in the tables 3.1
and 3.2. All identifiers for manufactures and device will exhibit odd parity with DQ
