Address: 0081H/1081H
Address: 0082H/1082H, 0083H/1083H
Address: 0084H/1084H
Notes 1.
Caution Be sure to clear bits 7 to 1 to “0”.
Note Be sure to set 00H to 0082H and 0083H, as these addresses are reserved areas. Also set 00H to 1082H
Note To use the on-chip debug function, set 02H or 03H to 0084H. Set a value that is the same as that of 0084H
Remark For the on-chip debug security ID, see CHAPTER 25 ON-CHIP DEBUG FUNCTION.
and 1083H because 0082H and 0083H are switched with 1082H and 1083H when the boot swap operation
is used.
to 1084H because 0084H and 1084H are switched during the boot swap operation.
2.
POCMODE
POCMODE can only be written by using a dedicated flash memory programmer. It cannot be set
during self-programming or boot swap operation during self-programming (at this time, 1.59 V POC
mode (default) is set). However, because the value of 1081H is copied to 0081H during the boot swap
operation, it is recommended to set a value that is the same as that of 0081H to 1081H when the boot
swap function is used.
To change the setting for the POC mode, set the value to 0081H again after batch erasure (chip
erasure) of the flash memory. The setting cannot be changed after the memory of the specified block
is erased.
