Section 28 Power-Down Modes
28.8
28.8.1
If a SLEEP instruction is executed when the SSBY bit in SBYCR has been set to 1, a transition to
software standby mode is made. In this state, if the CPSBY bit in DPSBYCR is set to 1, a
transition to deep software standby mode is made.
If a software standby mode clearing source (an NMI, IRQ0 to IRQ11, 32K timer, voltage-
monitoring interrupt requests*, or USB suspend/resume) occurs when a transition to software
standby mode is made, software standby mode will be cleared regardless of the DPSBY bit
setting, and the interrupt exception handling starts after the oscillation settling time for software
standby mode specified by the bits STS4 to STS0 in SBYCR has elapsed.
When both of the SSBY bit in SBYCR and the CPSBY bit in DPSBYCR are set to 1 and no
software standby mode clearing source occurs, a transition to deep software standby mode will be
made immediately after software standby mode is entered.
In deep software standby mode, the CPU, on-chip peripheral functions (except for the USB and
32K timer), on-chip RAM 4, and oscillator functionality are all stopped. In addition, the internal
power supply to these modules stops, resulting in a significant reduction in power consumption.
At this time, the contents of all the registers of the CPU, on-chip peripheral functions (except for
the USB and 32K timer), and on-chip RAM 4 become undefined.
Contents of the on-chip RAMs 3 to 0 and USB registers can be retained when all the bits
RAMCUT2 to RAMCUT0 in DPSBYCR have been cleared to 0. If these bits are set to all 1, the
internal power supply to the on-chip RAMs 3 to 0 and USB stops and the power consumption is
further reduced. At this time, the contents of the on-chip RAMs 3 to 0 and USB registers become
undefined.
The 32K timer, voltage detection circuit*, and power-on reset circuit* can be operated in deep
software standby mode.
The I/O ports can be retained in the same state as in software standby mode.
Note: * Supported only by the H8SX/1665M Group.
