6.2.1 Power Modes
PSoC 5 devices have four different power modes, as shown in
Table 6-2
easily provide required functionality and processing power while
simultaneously minimizing power consumption and maximizing
battery life in low power and portable devices.
PSoC 5 power modes, in order of decreasing power
consumption are:

disabled by using separate power configuration template
registers. In alternate active mode, fewer subsystems are
enabled, reducing power. In sleep mode most resources are
disabled regardless of the template settings. Sleep mode is
optimized to provide timed sleep intervals and RTC functionality.
The lowest power mode is hibernate, which retains register and
SRAM state, but no clocks, and allows wakeup only from I/O
pins.
