25. FLASH PROGRAMMING
The Device Configuration Area can be programmed or left un-
programmed to select device configuration such as security bit.
This area is not accessible during normal execution but is read-
able and writable during FLASH program / verify mode. The De-
vice Configuration Area register is located at the address 20FF
H
.
Figure 25-1 Device Configuration Area
25.1 Lock bit
The lock bit exists in Device Configuration Area register. If lock
bit is programmed and user tries to read FLASH memory cell, the
output data from the data port is 5AH that means the normal pro-
tection operation of user program data.Once the lock bit is pro-
grammed, the user can't modify and read the data of user program
area.
25.2 Power Fail Detector
The power fail detection provides 3 level of detection, 2.4V, 2.7V
and 3.0V. The default level of detection is 2.7V and this level is
applied if user does not select the specific level in FLASH pro-
gramming S/W tools. For more information, Refer to “24. POW-
ER FAIL PROCESSOR” on page 105.
