Section 28 Power-Down Modes
28.3.4
(1)
The LSI switches from a program execution state to deep standby mode by executing the SLEEP
instruction when the STBY bit and DEEP bit in STBCR are set to 1. In deep standby mode, not
only the CPU, clocks, and on-chip peripheral modules but also power supply is turned off
excluding the on-chip RAM (for data retention) retaining area specified by the RRAMKP3 to
RRAMKP0 bits in DSCTR and RTC. This can significantly reduce power consumption.
Therefore, data in the registers of the CPU, cache, and on-chip peripheral modules are not
retained. Pin state values immediately before the transition to deep standby mode are retained.
The CPU takes one cycle to finish writing to DSCTR, and then executes processing for the next
instruction. However, it actually takes one or more cycles to write. Therefore, execute a SLEEP
instruction after reading DSCTR to reflect the values written to DSCTR by the CPU in the SLEEP
instruction without fail.
The procedure for switching to deep standby mode is as follows. Figure 28.2 also shows its
flowchart.
1. To ensure that data is actually retained in deep standby mode by the on-chip RAM (for data

pin to be used for cancellation. In this case, also set the input signal detection mode (using
interrupt control registers 0 and 1 (ICR0 and ICR1) of the interrupt controller (INTC)) for the
pin used for cancellation. In the case of deep standby mode, only rising- or falling-edge
detection is valid. (Low-level detection or both-edge detection of the IRQ signal cannot be
used to cancel deep standby mode.)

data retention) after this time, execute this processing after the last write to the on-chip RAM
