5 / 17 page CAT25010, CAT25020, CAT25040 © Catalyst Semiconductor, Inc. 5 Doc. No. MD-1006 Rev. T Characteristics subject to change without notice STATUS REGISTER The Status Register, as shown in Table 2, contains a number of status and control bits. The RDY ¯¯¯¯ (Ready) bit indicates whether the device is busy with a write operation. This bit is automatically set to 1 during an internal write cycle, and reset to 0 when the device is ready to accept commands. For the host, this bit is read only. The WEL (Write Enable Latch) bit is set/reset by the WREN/WRDI commands. When set to 1, the device is in a Write Enable state and when set to 0, the device is in a Write Disable state. The BP0 and BP1 (Block Protect) bits determine which blocks are currently write protected. They are set by the user with the WRSR command and are non-volatile. The user is allowed to protect a quarter, one half or the entire memory, by setting these bits according to Table 3. The protected blocks then become read-only. Table 2.
