The Write Enable Latch (WEL) bit indicates the status
of the write enable latch. When WEL = 1, the latch is
set HIGH and when WEL = 0 the latch is reset LOW.
The WEL bit is a volatile, read only bit. It can be set by
the WREN instruction and can be reset by the WRDS
instruction.
The block lock bits, BL0 and BL1, set the level of block
lock protection. These nonvolatile bits are programmed
using the WRSR instruction and allow the user to pro-
tect one quarter, one half, all or none of the EEPROM
array. Any portion of the array that is block lock pro-
tected can be read but not written. It will remain pro-
tected until the BL bits are altered to disable block lock
protection of that portion of memory.
The watchdog timer bits, WD0 and WD1, select the
watchdog time out period. These nonvolatile bits are
programmed with the WRSR instruction.
The FLAG bit shows the status of a volatile latch that
can be set and reset by the system using the SFLB
and RFLB instructions. The flag bit is automatically
reset upon power up. This flag can be used by the sys-
tem to determine whether a reset occurs as a result of
a watchdog time out or power failure.
The nonvolatile WPEN bit is programmed using the
WRSR instruction. This bit works in conjunction with the
WP pin to provide an in-circuit programmable ROM func-
tion (Table 2). WP is LOW and WPEN bit programmed
HIGH disables all status register write operations.
In Circuit Programmable ROM Mode
This mechanism protects the block lock and watchdog
bits from inadvertent corruption.
In the locked state (
programmable ROM mode) the WP
pin is LOW and the nonvolatile bit WPEN is “1”. This
mode disables nonvolatile writes to the device’s status
register.
