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 1082 and

used.

AND 78F0386D ONLY).
POCMODE
POCMODE can only be written by using a dedicated flash 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.
Be sure to set 00H (on-chip debug operation disabled) to 0084H for products not equipped with the on-
chip debug function ( PD78F0372, 78F0373, 78F0374, 78F0375, 78F0376, 78F0382, 78F0383,
78F0384, 78F0385, and 78F0386). Also set 00H to 1084H because 0084H and 1084H are switched at
boot swapping.
To use the on-chip debug function with products equipped with the on-chip debug function
( PD78F0376D and 78F0386D), set 02H or 03H to 0084H. Set a value that is the same as that of
0084H to 1084H because 0084H and 1084H are switched at boot swapping.
