Functional Description
Run, wait, and stop modes provide means of enabling/disabling the peripheral and/or core
clocking as a group. The stop disable controls in the SDn registers override the default
behavior of stop mode. Asserting a peripheral's stop disable bit means the peripheral's
clock continues to operate in stop mode. This option is useful for generating interrupts
that return the device from stop to run mode.
On-chip peripherals run at the IP bus clock (peripheral bus) frequency,
same as the main processor frequency in this architecture. The maximum frequency of
operation is sys_clk=60 MHz. The only exceptions are the general-purpose timers and
SCIs, which can be configured to operate at two times the system bus rate using
TMRn_CR and SCIn_CR controls.
Run, wait, and stop modes may be combined with the low power modes of the PS and
choice of clocks to provide a broad palette of power control techniques.
