Write Enable (EEWREN) and Write
Disable (EEWRDI)
The MCP795WXX contains a write enable latch.
This latch must be set before any EEWRITE,
SRWRITE and IDWRITE operation will be completed
internally. The EEWREN instruction will set the latch, and
the EEWRDI will reset the latch.
The following is a list of conditions under which the
write enable latch will be reset:
Power-up
EEWRDI instruction successfully executed
SRWRITE instruction successfully executed
EEWRITE instruction successfully executed
IDWRITE instruction successfully executed
