3.4.1
This mode is unique among the three low-power Idle
modes in that it does not disable the primary device
clock. For timing sensitive applications, this allows for
the fastest resumption of device operation, with its
more accurate primary clock source, since the clock
source does not have to “warm up” or transition from
another oscillator.
PRI_IDLE mode is entered from PRI_RUN mode by
setting the IDLEN bit and executing a SLEEP
instruction. If the device is in another Run mode, set
IDLEN first, then clear the SCS bits and execute
SLEEP. Although the CPU is disabled, the peripherals
continue to be clocked from the primary clock source
specified by the FOSC3:FOSC0 Configuration bits.
The OSTS bit remains set (see Figure 3-7).
When a wake event occurs, the CPU is clocked from the
primary clock source. A delay of interval T
required between the wake event and when code
execution starts. This is required to allow the CPU to
become ready to execute instructions. After the wake-
up, the OSTS bit remains set. The IDLEN and SCS bits
are not affected by the wake-up (see Figure 3-8).

3.4.2
In SEC_IDLE mode, the CPU is disabled but the
peripherals continue to be clocked from the Timer1
oscillator. This mode is entered from SEC_RUN by
setting the IDLEN bit and executing a SLEEP
instruction. If the device is in another Run mode, set
IDLEN first, then set SCS1:SCS0 to ‘01’ and execute
SLEEP. When the clock source is switched to the
Timer1 oscillator, the primary oscillator is shut down,
the OSTS bit is cleared and the T1RUN bit is set.
When a wake event occurs, the peripherals continue to
be clocked from the Timer1 oscillator. After an interval of
T
ing code being clocked by the Timer1 oscillator. The
IDLEN and SCS bits are not affected by the wake-up;
the Timer1 oscillator continues to run (see Figure 3-8).

Note:
following the wake event, the CPU begins execut-
SEC_IDLE MODE
The Timer1 oscillator should already be
running prior to entering SEC_IDLE mode.
If the T1OSCEN bit is not set when the
SLEEP instruction is executed, the SLEEP
instruction will be ignored and entry to
SEC_IDLE mode will not occur. If the
Timer1 oscillator is enabled but not yet run-
ning, peripheral clocks will be delayed until
the oscillator has started. In such situations,
initial oscillator operation is far from stable
and unpredictable operation may result.
