low-power modes (continued)
Two control bits, LPM(1) and LPM(0), specify which of the three possible low-power modes is entered when
the IDLE instruction is executed (see Table 12). These bits are located in the System Control and Status
Register (SCSR) described in the TMS320C241/C242/C243 DSP Controllers CPU, System, Instruction Set,
and Peripherals Reference Guide (literature number SPRU276).

reset
A reset (from any source) causes the device to exit any of the IDLE modes. If the device is halted, the reset will
first start the oscillator, and there can be a delay while the oscillator powers up before clocks are generated to
initiate the CPU reset sequence.
external interrupts
The external interrupts, XINTx, can cause the device to exit any of the low-power modes, except HALT. If the
device is in IDLE2 mode, the synchronous logic connected to the external interrupt pins is bypassed with
combinatorial logic which recognizes the interrupt on the pin, starts the clocks, and then allows the clocked logic
to generate an interrupt request to the PIE controller. Note that in Table 12, external interrupts include PDPINT.
wakeup interrupts
Certain peripherals (for example, the CAN wakeup interrupt which can assert the CAN error interrupt request
even when there are no clocks running) can have the capability to start the device clocks and then generate
an interrupt in response to certain external events, for example, activity on a communication line.
