4.3.5 STOP-D Mode
The STOP-D mode has, in addition to the functionality of the STOP mode described in the previous section, an
additional control function to decrease the voltage of internal logic power (V
DDL
). The current consumption can be
further reduced due to lowering of the V
DDL
voltage. See section "4.3.7 Operation of Each Function in Standby Mode"
for the operation of each function in the STOP-D mode.
See Table 4-5 for a comparison of time for restoring (start-up time) from STOP and STOP-D modes.
To enter the STOP-D mode, write "0x5n" then "0xAn" (n = arbitrary) to the STPACP register to enable the transition to
the STOP/STOP-D mode, then write "1" to the STPD bit of the SBYCON register.
The STOP-D mode is released by the external interrupts, voltage level supervisor (VLS) or interrupt requests from the
analog comparator. It returns to the program run mode with the SYSTEMCLK chosen before entering the STOP-D
mode.
Figure 4-6 shows the STOP-D mode operation waveforms of the low-speed oscillation circuit.
Figure 4-7 shows the STOP-D mode operation waveforms of the PLL oscillation circuit.
