Refer to DC Characteristics. When VPEN</= VPENLK, memory contents can be read but not altered
X can be VIL or VIH for control and address pins, and VPENLK or VPENH for VPEN. See DC Characteristics for VPENLK and VPENH voltages
In default mode, STA is VOL when the ISM is executing internal Block Erase, Program, or lock bit configuration algorithms. It is VOH when the ISM
is not busy, in block erase suspend mode, program suspend mode, or reset/power-down mode.
See Read Identifier codes of the Micron Datasheet (DS)
See Read Query Mode Command section of the Micron Datasheet (DS)
Command Writes involving block erase, program, or lock bit configuration are reliably executed when VPEN=VPENH and VCC is within Specification
Refer to Table 4 on page 15 of the Micron Datasheet (DS)

Includes STS
ICCWS and ICCES are specified with the device deselected. If the device is read or written while in ERASE SUSPEND mode,
the device's curent draw is ICCR or ICCW
BLOCK ERASE, PROGRAMMING, and LOCK BIT configurations are inhibited when VPEN</= VPENLK, and they are not
guaranteed in the range betwwn VPENLK (MAX) and VPENH (MIN), or above VPENH (Max)
Typically, VPEN is connected to VCC
VPENH (MIN) = 2.7v
