Preliminary Data Sheet
10. PMU (POWER MANAGEMENT UNIT)
10.1 General
PMU manages and controls power to the internal and external circuits of the V
R
4102 as follows:
Controls shutdown
Controls reset
Controls power-ON
Controls low-power consumption mode
PMU also set the start cause via the GPIO (0:3), (9:12) pins and DCD# pin.

Function
0x0B00 00A0
PMUINTREG
PMU interrupt/status register
0x0B00 00A2
PMUCNTREG
PMU control register
10.2 Power Mode
The V
R
4102 supports the following four power modes:
Fullspeed mode
Standby mode
Suspend mode
Hibernate mode
Figure 10-1 illustrates the transition of the power modes.
To change the mode from Fullspeed to Standby, Suspend, or Hibernate, execute the STANDBY, SUSPEND, or
HIBERNATE instruction. To change the mode from Standby, Suspend, or Hibernate to Fullspeed, either generate an
interrupt, or execute a reset operation.
Table 10-2 outlines each power mode.
