Section 28 Power-Down Modes
28.2.13 Deep Standby Cancel Source Flag Register (DSFR)
DSFR is a 16-bit readable/writable register composed of two types of bits. One is the flag that
confirms which interrupt canceled deep standby mode. The other is the bit that releases the state of
pins after canceling deep standby mode. When deep standby mode is canceled by an interrupt
(NMI or IRQ) or a manual reset, this register retains the previous data although power-on reset
exception handling is executed. When deep standby mode is canceled by a power-on reset, this
register is initialized to H’0000. Only word access is valid.
All flags must be cleared immediately before transition to deep standby mode.
Note: When writing to this register, see section 28.4, Usage Notes.

Description
Release of Pin State Retention
Releases the retention of the pin state after canceling
deep standby mode
0: Pin state not retained
[Clearing condition]
Writing 0
1: Pin state retained
[Setting condition]
When deep standby mode is entered
Reserved
These bits are always read as 0. The write value
should always be 0.
MRES Flag
