Status and Control Registers - Descriptions and Commands

The ATXP032 has three Volatile Status and Control registers as listed in Table 12-1, and two Nonvolatile Status

and Control registers as listed in Table 12-2, one of which is reserved. All Status and Control registers can be read

and written by the generic Read Status Registers (65h) and Write Status Registers (71h).

For backward compatibility, the specific Read Status Register Byte 1 (05h) command is also supported for

Status/Control Register Byte 1, and the specific Write Status Register Byte 1 (01h) and Write Status Register Byte

2 (31h) commands are supported for Status/Control register 1 and 2. Note that the behavior of the Read Status

Status/Control Register Byte 1.

When writing to registers, bits that are read only or reserved for future use should be written as 0. All volatile or

non-volatile registers may be written in a single operation by using the Write Status Registers (71h) command. It is

not recommended to try to write both the volatile and the non-volatile registers at the same time. Non-volatile

registers are only written if the Write Status Registers (71h) command specifies the address of a non-volatile

Non-volatile registers are typically only written once, at the initial configuration of the device. Volatile registers have

to be re-written every time the device is powered up or wakes up from ultra-deep power down.
