CAT25640
Write Status Register
The Status Register is written by sending a WRSR
instruction according to timing shown in Figure 7. Only bits
2, 3 and 7 can be written using the WRSR command.
Write Protection
The Write Protect (WP) pin can be used to protect the
Block Protect bits BP0 and BP1 against being inadvertently
altered. When WP is low and the WPEN bit is set to “ 1”,
write operations to the Status Register are inhibited. WP
going low while CS is still low will interrupt a write to the
status register. If the internal write cycle has already been
initiated, WP going low will have no effect on any write
operation to the Status Register. The WP pin function is
blocked when the WPEN bit is set to “0”. The WP input
timing is shown in Figure 8.
