The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV004TC/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 (MBM29LV004TC = B5H and MBM29LV004BC = B6H). These two bytes/words are given in the tables 3.1
