Three different power reduction modes with different levels of power reduction have
been implemented in the INCA-D.
In Idle mode the CPU is stopped, while the peripherals continue their operation, i.e. the
clock of the XBUS is still running.
Idle mode can be terminated by any reset or interrupt request.
In Power Down mode both the CPU and the peripherals are stopped, because the
XBUS clock gets killed.
Power Down mode can only be terminated by a hardware reset.
The Sleep mode is similar to Power Down mode, but the power consumption is further
reduced, because the oscillator is switched off additionally.
An external interrupt at FEXT1 (P2.1) or an interrupt caused by the DASL line (Level
Detect) wakes up the device from sleep mode.
Note: All external bus actions are completed before Idle, Sleep or Power Down mode of
23.1
The Sleep mode is the most effective power reduction mode.
To enter sleep mode bit OSC_DWN has to be set to '1', while pin FEXT1 is configured
as input and driven 'high'
After an interrupt at FEXT1 or LD (ie. some activity on the Line), the the osc wakes up
again. To enable the wakeup from the line, bit EA_FIR has to be set to 1.
