The device provides two power saving modes of operation for applications where power
consumption is critical. The two modes are Idle and Power-down, see
Idle mode is entered by setting the IDL bit in the PCON register. In Idle mode, the Program
Counter (PC) is stopped. The system clock continues to run and all interrupts and
peripherals remain active. The on-chip RAM and the special function registers hold their
data during this mode.
