Output Driver Strength (DRV1, DRV0) –
Volatile/Non-Volatile Writable
The DRV1 & DRV0 bits are used to determine the output driver strength for the Read operations.

/HOLD or /RESET Pin Function (HOLD/RST) –
Volatile/Non-Volatile Writable
The HOLD/RST bit is used to determine whether /HOLD or /RESET function should be implemented on
the hardware pin. When HOLD/RST=0 (factory default), the pin acts as /HOLD; when HOLD/RST=1, the
pin acts as /RESET. However, /HOLD or /RESET functions are only available when QE=0. If QE is set to
1, the /HOLD and /RESET functions are disabled, the pin acts as a dedicated data I/O pin.
7.1.15
Reserved Bits –
Non Functional
There are a few reserved Status Register bits that may be read out as a “0” or “1”. It is recommended to
ignore the values of those bits. During a “Write Status Register” instruction, the Reserved Bits can be
written as “0”, but there will not be any effects.
