BP2, BP1, BP0: Block Protect Bits (Nonvolatile)  
ers up again. Writes to the WEL bit do not cause a non-  
volatile write cycle, so the device is ready for the next  
operation immediately after the stop condition.  
The Block Protect Bits, BP2, BP1 and BP0, determine  
which blocks of the array are write protected. A write to a  
protected block of memory is ignored. The block protect  
bits will prevent write operations to the following seg-  
ments of the array.  
WD1, WD0: Watchdog Timer Bits  
The bits WD1 and WD0 control the period of the Watch-  
dog Timer. The options are shown below.

Write Protect Enable  
These devices have an advanced Block Lock scheme  
that protects one of five blocks of the array when  
enabled. It provides hardware write protection through  
the use of a WP pin and a nonvolatile Write Protect  
Enable (WPEN) bit.  
RWEL: Register Write Enable Latch (Volatile)  
The RWEL bit must be set to “1” prior to a write to the  
Control Register.  
The Write Protect (WP) pin and the Write Protect Enable  
(WPEN) bit in the Control Register control the program-  
mable Hardware Write Protect feature. Hardware Write  
Protection is enabled when the WP pin and the WPEN  
bit are HIGH and disabled when either the WP pin or the  
WPEN bit is LOW. When the chip is Hardware Write Pro-  
tected, nonvolatile writes to the block protected sections  
in the memory array cannot be written and the block pro-  
tect bits cannot be changed. Only the sections of the  
memory array that are not block protected can be writ-  
ten. Note that since the WPEN bit is write protected, it  
cannot be changed back to a LOW state; so write pro-  
tection is enabled as long as the WP pin is held HIGH.  
WEL: Write Enable Latch (Volatile)  
The WEL bit controls the access to the memory and to  
the Register during a write operation. This bit is a volatile  
latch that powers up in the LOW (disabled) state. While  
the WEL bit is LOW, writes to any address, including any  
control registers will be ignored (no acknowledge will be  
issued after the Data Byte). The WEL bit is set by writing  
a “1” to the WEL bit and zeroes to the other bits of the  
control register. Once set, WEL remains set until either it  
is reset to 0 (by writing a “0” to the WEL bit and zeroes to  
the other bits of the control register) or until the part pow-
