• Manufacturer Part Number: upd78f0114hgb-8es-a
• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

Address: 0080H/1080H
Address: 0081H/1081H, 0082H/1082H, 0083H/1083H
Note Set a value that is the same as that of 0080H to 1080H because 0080H and 1080H are switched during the

1081H, 1082H, and 1083H because 0081H, 0082H, and 0083H are switched with 1081H, 1082H, and
1083H when the boot swap operation is used.
2. Be sure to clear bit 2 to 7 to 0.
OSCSEL0
LSROSC
watchdog timer in the HALT and STOP modes, regardless of the setting of bit 0 (RSTOP) of
the internal oscillation mode register (RCM).
When 8-bit timer H1 operates with the internal oscillation clock, the count clock is supplied to
8-bit timer H1 even in the HALT/STOP mode.
