Result of the most recent Memory Page to Buffer Compare operation. If this bit is equal to 0, then the data in the main memory page matches the data in the buffer. If it's 1 then at least 1 byte in the main memory page does not match the data in the buffer.

| #define DEVICE_DENSITY 0x2C |
Bits 5, 4, 3 and 2 indicates the device density. The decimal value of these four binary bits does not equate to the device density; the four bits represent a combinational code relating to differing densities of DataFlash devices. The device density is not the same as the density code indicated in the JEDEC device ID information. The device density is provided only for backward compatibility.

| #define PAGE_SIZE 0x01 |
Bit 0 indicates wether the page size of the main memory array is configured for "power of 2" binary page size (512 bytes) (bit=1) or standard DataFlash page size (528 bytes) (bit=0).

| #define PROTECT 0x02 |
Bit 1 in the Status Register is used to provide information to the user whether or not the sector protection has been enabled or disabled, either by software-controlled method or hardware-controlled method. 1 means that the sector protection has been enabled and 0 that it has been disabled.
Definition at line 96 of file at45db161d.h.
| #define READY_BUSY 0x80 |
Ready/busy status is indicated using bit 7 of the status register. If bit 7 is a 1, then the device is not busy and is ready to accept the next command. If bit 7 is a 0, then the device is in a busy state.
