Flexible Clock Management
This module especially serves for power management support. Flexible clock
management includes programmable system slow down with additional control of power
down and optional real time clock. The slowdown operation is achieved by dividing the
oscillator clock by a programmable factor (1...32) resulting in a low frequency device
operation which significantly reduces the overall power consumption. The PLL may be
completely switched off in this mode.
This module also controls the oscillator selection (main or auxiliary) for Real Time Clock
and for Slow Down Divider. During Power Down mode, this block controls the operation
of RTC and ports.
The clock generation is controlled via register SYSCON2.
